Struct Feature

#[repr(C)]
pub struct Feature {
    pub tag: Tag,
    pub value: u32,
    pub start: u32,
    pub end: u32,
}

A feature tag with an accompanying range specifying on which subslice of shapes input it should be applied.

Fields

tag: Tag

value: u32

start: u32

end: u32

Implementations

impl Feature

pub fn new(tag: Tag, value: u32, range: impl RangeBounds<usize>) -> Feature

Create a new Feature struct.

Trait Implementations

impl Clone for Feature

fn clone(&self) -> Feature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Feature

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

Formats the value using the given formatter.

impl FromStr for Feature

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a Feature form a string.

Possible values:

• kern -> kern .. 1
• +kern -> kern .. 1
• -kern -> kern .. 0
• kern=0 -> kern .. 0
• kern=1 -> kern .. 1
• aalt=2 -> altr .. 2
• kern[] -> kern .. 1
• kern[:] -> kern .. 1
• kern[5:] -> kern 5.. 1
• kern[:5] -> kern ..=5 1
• kern[3:5] -> kern 3..=5 1
• kern[3] -> kern 3..=4 1
• aalt[3:5]=2 -> kern 3..=5 1

type Err = &'static str

The associated error which can be returned from parsing.

impl Hash for Feature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Feature

fn eq(&self, other: &Feature) -> 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.
