Trait Platform 

pub trait Platform {
    // Required method
    fn diagnostics(&self) -> &dyn DiagnosticSink;

    // Provided methods
    fn limits(&self) -> HostLimits { ... }
    fn clock(&self) -> HostClock { ... }
    fn linebreak_start(&self, _request: LinebreakRequest<'_>) { ... }
    fn linebreak_next(&self) -> Option<i32> { ... }
    fn host_box(&self, _request: HostBoxRequest) -> Option<HostBox> { ... }
}

Host runtime services that must remain separate from engine semantics.

Required Methods

fn diagnostics(&self) -> &dyn DiagnosticSink

Returns the diagnostic sink for this platform.

Provided Methods

fn limits(&self) -> HostLimits

Returns host resource limits, defaulting to HostLimits::default().

fn clock(&self) -> HostClock

Deterministic clock value visible to generated TeX code.

fn linebreak_start(&self, _request: LinebreakRequest<'_>)

Called before the engine begins line break iteration for a paragraph.

fn linebreak_next(&self) -> Option<i32>

Returns the next line break position, or None to use the built in algorithm.

fn host_box(&self, _request: HostBoxRequest) -> Option<HostBox>

Returns the box for a host owned token, or None to typeset a zero size box.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
