Struct RendererFontEnvironmentSnapshot 

pub struct RendererFontEnvironmentSnapshot {
    pub revision: u64,
    pub text_font_stack_key: Option<u64>,
    pub sources: Vec<RendererFontSourceRecord>,
}

Best-effort snapshot of font sources currently known to the runner-owned renderer environment.

This is intentionally source-oriented rather than family-oriented:

• FontCatalogMetadata remains the best-effort family picker surface,
• TextFontStackKey remains the cross-surface invalidation key,
• and this snapshot records where the renderer’s currently approved font bytes came from.

revision is monotonic and should advance whenever the effective renderer text environment changes in a way that can affect downstream consumers such as future SVG-text bridges.

Fields

revision: u64

text_font_stack_key: Option<u64>

sources: Vec<RendererFontSourceRecord>

Implementations

impl RendererFontEnvironmentSnapshot

pub fn extend_sources_unique( &mut self, sources: impl IntoIterator<Item = RendererFontSourceRecord>, ) -> bool

Trait Implementations

impl Clone for RendererFontEnvironmentSnapshot

fn clone(&self) -> RendererFontEnvironmentSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RendererFontEnvironmentSnapshot

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

Formats the value using the given formatter.

impl Default for RendererFontEnvironmentSnapshot

fn default() -> RendererFontEnvironmentSnapshot

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RendererFontEnvironmentSnapshot

where RendererFontEnvironmentSnapshot: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RendererFontEnvironmentSnapshot

fn eq(&self, other: &RendererFontEnvironmentSnapshot) -> 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 RendererFontEnvironmentSnapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
