Struct Modifier 

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

Bitset of style modifiers (bold, italic, etc.).

Implemented as a plain u8 rather than bitflags! to keep the crate’s dependency cone untouched. The bit layout is private; use the named constants and BitOr operator to compose values.

Combining modifiers with | and testing membership with Modifier::contains is the intended composition pattern. Pair Modifier::REVERSED with a semantic colour from super::palette to satisfy the project’s accessibility contract (color is never the sole distinguishing signal).

Examples

use rlevo_core::render::styled::Modifier;

let m = Modifier::BOLD | Modifier::UNDERLINED;
assert!(m.contains(Modifier::BOLD));
assert!(m.contains(Modifier::UNDERLINED));
assert!(!m.contains(Modifier::ITALIC));

// Hue-redundant hazard signal: combine REVERSED with a red foreground.
let hazard = Modifier::BOLD | Modifier::REVERSED;
assert!(hazard.contains(Modifier::REVERSED));

Implementations

impl Modifier

pub const EMPTY: Self

No modifiers set.

pub const BOLD: Self

Bold text.

pub const DIM: Self

Dim / faint text.

pub const ITALIC: Self

Italic text.

pub const UNDERLINED: Self

Underlined text.

pub const REVERSED: Self

Reversed foreground/background. Pairs with HAZARD_FG to add the hue-redundant signal required by the project accessibility contract.

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

true when every bit of other is set in self.

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

Return the union of two modifier sets.

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

Return the intersection of two modifier sets.

pub const fn insert(&mut self, other: Self)

Insert other’s bits in place.

pub const fn remove(&mut self, other: Self)

Clear other’s bits in place.

pub const fn is_empty(self) -> bool

true when no bits are set.

pub const fn bits(self) -> u8

Raw bit value. Intended for renderer-side bit translation (e.g., mapping into ratatui::style::Modifier) — not part of the public styling contract.

Trait Implementations

impl BitOr for Modifier

type Output = Modifier

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for Modifier

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for Modifier

fn clone(&self) -> Modifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Modifier

impl Debug for Modifier

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

Formats the value using the given formatter.

impl Default for Modifier

fn default() -> Modifier

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Modifier

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Modifier

impl PartialEq for Modifier

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

impl Serialize for Modifier

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Modifier
