Struct ethers_solc::AllowedLibPaths

pub struct AllowedLibPaths(/* private fields */);

Helper struct for serializing --allow-paths arguments to Solc

From the Solc docs: For security reasons the compiler has restrictions on what directories it can access. Directories of source files specified on the command line and target paths of remappings are automatically allowed to be accessed by the file reader, but everything else is rejected by default. Additional paths (and their subdirectories) can be allowed via the –allow-paths /sample/path,/another/sample/path switch. Everything inside the path specified via –base-path is always allowed.

Implementations

impl AllowedLibPaths

pub fn args(&self) -> Option<[String; 2]>

Returns the Command arguments for this type

--allow-paths takes a single value: all comma separated paths

pub fn paths(&self) -> impl Iterator<Item = &PathBuf> + '_

Returns all paths that exist

Methods from Deref<Target = BTreeSet<PathBuf>>

pub fn range<K, R>(&self, range: R) -> Range<'_, T>

where K: Ord + ?Sized, T: Borrow<K> + Ord, R: RangeBounds<K>,

Constructs a double-ended iterator over a sub-range of elements in the set. The simplest way is to use the range syntax min..max, thus range(min..max) will yield elements from min (inclusive) to max (exclusive). The range may also be entered as (Bound<T>, Bound<T>), so for example range((Excluded(4), Included(10))) will yield a left-exclusive, right-inclusive range from 4 to 10.

Panics

Panics if range start > end. Panics if range start == end and both bounds are Excluded.

Examples

use std::collections::BTreeSet;
use std::ops::Bound::Included;

let mut set = BTreeSet::new();
set.insert(3);
set.insert(5);
set.insert(8);
for &elem in set.range((Included(&4), Included(&8))) {

where T: Borrow<Q> + Ord, Q: Ord + ?Sized,

    assert_eq!(n, 1);
}
assert!(set.is_empty());

pub fn insert(&mut self, value: T) -> bool

where T: Ord,

Adds a value to the set.

Returns whether the value was newly inserted. That is:

• If the set did not previously contain an equal value, true is returned.
• If the set already contained an equal value, false is returned, and the entry is not updated.

See the module-level documentation for more.

Examples

use std::collections::BTreeSet;

The value may be any borrowed form of the set’s element type, but the ordering on the borrowed form must match the ordering on the element type.

Examples

use std::collections::BTreeSet;

let mut set = BTreeSet::from([1, 2, 3]);
assert_eq!(set.take(&2), Some(2));
assert_eq!(set.take(&2), None);

pub fn retain<F>(&mut self, f: F)

where T: Ord, F: FnMut(&T) -> bool,

let mut b = BTreeSet::new();
b.insert(3);
b.insert(4);
b.insert(5);

a.append(&mut b);

assert_eq!(a.len(), 5);
assert_eq!(b.len(), 0);

assert!(a.contains(&1));
assert!(a.contains(&2));
assert!(a.contains(&3));
assert!(a.contains(&4));
assert!(a.contains(&5));

pub fn split_off<Q>(&mut self, value: &Q) -> BTreeSet<T, A>

let mut a = BTreeSet::new();
a.insert(1);
a.insert(2);
a.insert(3);
a.insert(17);
a.insert(41);

let b = a.split_off(&3);

assert_eq!(a.len(), 2);
assert_eq!(b.len(), 3);

assert!(a.contains(&1));
assert!(a.contains(&2));

assert!(b.contains(&3));
assert!(b.contains(&17));
assert!(b.contains(&41));

pub fn extract_if<'a, F>(&'a mut self, pred: F) -> ExtractIf<'a, T, F, A>

where T: Ord, F: 'a + FnMut(&T) -> bool,

🔬This is a nightly-only experimental API. (btree_extract_if)

Creates an iterator that visits all elements in ascending order and uses a closure to determine if an element should be removed.

If the closure returns true, the element is removed from the set and yielded. If the closure returns false, or panics, the element remains in the set and will not be yielded.

If the returned ExtractIf is not exhausted, e.g. because it is dropped without iterating or the iteration short-circuits, then the remaining elements will be retained. Use retain with a negated predicate if you do not need the returned iterator.

Examples

Splitting a set into even and odd values, reusing the original set:

#![feature(btree_extract_if)]
use std::collections::BTreeSet;

let mut set: BTreeSet<i32> = (0..8).collect();
let evens: BTreeSet<_> = set.extract_if(|v| v % 2 == 0).collect();
let odds = set;
assert_eq!(evens.into_iter().collect::<Vec<_>>(), vec![0, 2, 4, 6]);
assert_eq!(odds.into_iter().collect::<Vec<_>>(), vec![1, 3, 5, 7]);

pub fn iter(&self) -> Iter<'_, T>

Gets an iterator that visits the elements in the BTreeSet in ascending order.

Examples

use std::collections::BTreeSet;

let set = BTreeSet::from([3, 1, 2]);
let mut set_iter = set.iter();
assert_eq!(set_iter.next(), Some(&1));
assert_eq!(set_iter.next(), Some(&2));
assert_eq!(set_iter.next(), Some(&3));
assert_eq!(set_iter.next(), None);

pub fn len(&self) -> usize

Returns the number of elements in the set.

Examples

use std::collections::BTreeSet;

let mut v = BTreeSet::new();
assert_eq!(v.len(), 0);
v.insert(1);
assert_eq!(v.len(), 1);

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

Examples

use std::collections::BTreeSet;

let mut v = BTreeSet::new();
assert!(v.is_empty());
v.insert(1);
assert!(!v.is_empty());
