Struct InputState 

pub struct InputState {
    pub stack: Vec<Level>,
    pub param_stack: Vec<TokenList>,
    pub align_state: i32,
    pub scanner_status: ScannerStatus,
    pub warning_index: CsId,
    pub open_parens: usize,
    pub force_eof: bool,
    pub last_line: i32,
    pub in_open: usize,
    pub spare_tokens: Vec<TokenList>,
}

The input stack.

Fields

stack: Vec<Level>

All levels; the last one is the current input (cur_input).

param_stack: Vec<TokenList>

Arguments of macros being expanded.

align_state: i32

Brace balance for alignments (align_state).

scanner_status: ScannerStatus

What the scanner is doing.

warning_index: CsId

The macro or definition being scanned, for diagnostics.

open_parens: usize

Number of open parentheses printed for input files.

force_eof: bool

Whether \endinput was seen in the current file.

last_line: i32

Line number of the most recent \read line, etc.

in_open: usize

Text levels open on files, \scantokens pseudo-files and \read streams (TeX’s in_open).

spare_tokens: Vec<TokenList>

One-token lists of backed-up levels that ended, for back_input to reuse (it runs very often; this saves an allocation each time).

Implementations

impl InputState

pub fn in_open(&self) -> usize

Number of text levels that are input files (TeX’s in_open).

pub fn cur_text(&self) -> Option<&TextLevel>

The innermost text level, if any.

pub fn line(&self) -> i32

The current line number (line): the line of the innermost file.

pub fn in_token_list(&self) -> bool

Whether the current level is a token list.

pub fn terminal_input(&self) -> bool

Whether we are reading from the terminal (terminal_input).

Trait Implementations

impl Debug for InputState

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

Formats the value using the given formatter.

impl Default for InputState

fn default() -> Self

Returns the “default value” for a type.
