Struct tfm::ligkern::lang::Program

pub struct Program {
    pub instructions: Vec<Instruction>,
    pub left_boundary_char_entrypoint: Option<u16>,
    pub right_boundary_char: Option<Char>,
    pub passthrough: HashSet<u16>,
}

A lig/kern program.

In theory the program also includes entrypoints. However because these are provided in different ways in .tfm and .pl files, it’s easier to exclude them on this type and pass them in when needed.

Fields

instructions: Vec<Instruction>

left_boundary_char_entrypoint: Option<u16>

right_boundary_char: Option<Char>

passthrough: HashSet<u16>

Implementations

impl Program

pub fn unpack_entrypoint( &mut self, entrypoint: u8, ) -> Result<u16, InvalidEntrypointError>

pub fn pack_entrypoints( &mut self, entrypoints: HashMap<Char, u16>, ) -> HashMap<Char, u8>

pub fn unpack_kerns(&mut self) -> Vec<FixWord>

pub fn pack_kerns(&mut self, kerns: &[FixWord])

pub fn reachable_iter<I: Iterator<Item = (Char, u16)>>( &self, entrypoints: I, ) -> ReachableIter<'_>

pub fn instructions_for_entrypoint( &self, entrypoint: u16, ) -> InstructionsForEntrypointIter<'_>

Iterate over the lig/kern instructions for a specific entrypoint.

pub fn is_seven_bit_safe(&self, entrypoints: HashMap<Char, u16>) -> bool

pub fn validate_and_fix<I, T>( &mut self, smallest_char: Char, entrypoints: I, char_exists: T, kerns: &[FixWord], ) -> Vec<ValidationWarning>

where I: Iterator<Item = (Char, u8)>, T: Fn(Char) -> bool,

Trait Implementations

impl Clone for Program

fn clone(&self) -> Program

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Program

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

Formats the value using the given formatter.

impl Default for Program

fn default() -> Program

Returns the “default value” for a type.

impl PartialEq for Program

fn eq(&self, other: &Program) -> 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.
