Struct State

pub struct State { /* private fields */ }

Simple state type for use in unit tests.

If the primitives under test don’t require custom components or other pieces in the state, it is easier to use this type rather than defining a custom one.

Implementations

impl State

pub fn get_integer() -> BuiltIn<State>

Trait Implementations

impl Default for State

fn default() -> State

Returns the “default value” for a type.

impl HasComponent<Component> for State

fn component(&self) -> &Component

Return a immutable reference to the component.

fn component_mut(&mut self) -> &mut Component

Return a mutable reference to the component.

impl HasComponent<Component> for State

fn component(&self) -> &Component

Return a immutable reference to the component.

fn component_mut(&mut self) -> &mut Component

Return a mutable reference to the component.

impl TexlangState for State

fn cat_code(&self, c: char) -> CatCode

Get the cat code for the provided character.

fn post_macro_expansion_hook( token: Token, input: &ExpansionInput<Self>, tex_macro: &Macro, arguments: &[&[Token]], reversed_expansion: &[Token], )

Hook that is invoked after a TeX macro is expanded.

fn expansion_override_hook( token: Token, input: &mut ExpansionInput<Self>, tag: Option<Tag>, ) -> Result<Option<Token>, Box<Error>>

Hook that potentially overrides the expansion of a command.

fn pre_source_code_addition_hook( token: Option<Token>, num_existing_sources: usize, ) -> Result<(), Box<Error>>

Hook that runs before new source code is added.

fn variable_assignment_scope_hook(state: &mut Self) -> Scope

Hook that determines the scope of a variable assignment.
