Struct Engine 

pub struct Engine { /* private fields */ }

The layout engine: a face roster plus the calibrated math constants.

Implementations

impl Engine

pub fn new(faces: FaceSet) -> Self

Build an engine over a face roster with the CM constants.

pub fn bundled() -> Result<Self, FontError>

The engine over the bundled sovereign face set.

Errors

Propagates a bundled-face parse failure (build corruption).

pub fn faces(&self) -> &FaceSet

The face roster.

pub fn constants(&self) -> &MathConstants

The math constants in force.

pub fn typeset(&self, source: &str, style: Style) -> Result<Layout, MathError>

Typeset a math-mode string at the given outer style.

Errors

Parse errors pass through; layout adds MathError::UnmappedChar for characters no face covers and named layout-pending errors for the extensions bead’s constructs.

pub fn typeset_text(&self, source: &str) -> Result<Layout, MathError>

Typeset a TexText-contract string (text mainland + math islands).

Errors

As Engine::typeset.

pub fn typeset_with_macros( &self, source: &str, style: Style, macros: &MacroSet, ) -> Result<Layout, MathError>

Engine::typeset, against a macro set (a preamble pack and/or caller definitions).

Errors

As Engine::typeset, plus the macro-expansion errors.

pub fn typeset_text_with_macros( &self, source: &str, macros: &MacroSet, ) -> Result<Layout, MathError>

Engine::typeset_text, against a macro set.

Errors

As Engine::typeset_with_macros.
