Implementationsยง

Sourceยง

impl GraphemeProps

Source

pub const fn new(gcb: GraphemePropCb, incb: GraphemePropInCb) -> Self

Creates a new property tuple from individual break properties.

Source

pub const fn for_charu(c: charu) -> Self

Looks up grapheme properties for a scalar.

Uses an embedded trie to find the Grapheme_Cluster_Break and Indic_Conjunct_Break properties for the scalar.

Source

pub const fn for_char(c: char) -> Self

Looks up grapheme properties for a scalar.

Convenience method that converts to charu internally. Prefer for_charu if you already have a charu.

Source

pub const fn gcb_property(self) -> GraphemePropCb

Returns the Grapheme_Cluster_Break property.

ยงFeatures

Uses the unsafe_layout feature to transmute instead of match.

Source

pub const fn incb_property(self) -> GraphemePropInCb

Returns the Indic_Conjunct_Break property.

ยงFeatures

Uses the unsafe_layout feature to transmute instead of match.

Source

pub const fn is_any_control(self) -> bool

Returns true if this code point is a control code point.

Source

pub const fn eq(self, other: Self) -> bool
