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> { ... }
}

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.

Dyn Compatibility

This trait is dyn compatible.

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