Struct Attributes

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

GFF record attributes.

Attributes are extra data attached to a GFF record. They are represented as a typed map, where each key (Tag) is associated with a typed Value.

Implementations

impl Attributes

pub fn is_empty(&self) -> bool

Returns whether there are any entries.

pub fn len(&self) -> usize

Returns the number of entries.

pub fn get(&self, tag: &str) -> Option<&Value>

Returns the value at the given tag.

Trait Implementations

impl AsMut<IndexMap<String, Value>> for Attributes

fn as_mut(&mut self) -> &mut IndexMap<Tag, Value>

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<IndexMap<String, Value>> for Attributes

fn as_ref(&self) -> &IndexMap<Tag, Value>

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl Extend<(String, Value)> for Attributes

fn extend<T: IntoIterator<Item = (Tag, Value)>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl FromIterator<(String, Value)> for Attributes

fn from_iter<T: IntoIterator<Item = (Tag, Value)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
