Struct solana_sdk::syscall::slot_hashes::SlotHashes

pub struct SlotHashes { /* fields omitted */ }

Methods

impl SlotHashes

pub fn from(account: &Account) -> Option<Self>

pub fn to(&self, account: &mut Account) -> Option<()>

pub fn size_of() -> usize

pub fn add(&mut self, slot: u64, hash: Hash)

Methods from Deref<Target = Vec<(u64, Hash)>>

pub fn capacity(&self) -> usize

Returns the number of elements the vector can hold without reallocating.

Examples

let vec: Vec<i32> = Vec::with_capacity(10);
assert_eq!(vec.capacity(), 10);

pub fn as_slice(&self) -> &[T]

Extracts a slice containing the entire vector.

Equivalent to &s[..].

Examples

use std::io::{self, Write};
let buffer = vec![1, 2, 3, 5, 8];
io::sink().write(buffer.as_slice()).unwrap();

pub fn len(&self) -> usize

Returns the number of elements in the vector, also referred to as its 'length'.

Examples

let a = vec![1, 2, 3];
assert_eq!(a.len(), 3);

pub fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

Examples

let mut v = Vec::new();
assert!(v.is_empty());

v.push(1);
assert!(!v.is_empty());
