Struct StrInput

pub struct StrInput<'a> { /* private fields */ }

A parser input that uses a &str as source.

Implementations

impl<'a> StrInput<'a>

pub fn new(input: &'a str) -> Self

Create a new StrInput with the given str.

Trait Implementations

impl<'a> Input for StrInput<'a>

fn lookahead(&mut self, x: usize)

A hint to the input source that we will need to read count characters.

fn buflen(&self) -> usize

Return the number of buffered characters in self.

fn bufmaxlen(&self) -> usize

Return the capacity of the buffer in self.

fn buf_is_empty(&self) -> bool

Return whether the buffer (!= stream) is empty.

fn raw_read_ch(&mut self) -> char

Read a character from the input stream and return it directly.

fn raw_read_non_breakz_ch(&mut self) -> Option<char>

Read a non-breakz a character from the input stream and return it directly.

fn skip(&mut self)

Consume the next character.

fn skip_n(&mut self, count: usize)

Consume the next count character.

fn peek(&self) -> char

Return the next character, without consuming it.

fn peek_nth(&self, n: usize) -> char

Return the n-th character in the buffer, without consuming it.

fn look_ch(&mut self) -> char

Look for the next character and return it.

fn next_char_is(&self, c: char) -> bool

Return whether the next character in the input source is equal to c.

fn nth_char_is(&self, n: usize, c: char) -> bool

Return whether the n-th character in the input source is equal to c.

fn next_2_are(&self, c1: char, c2: char) -> bool

Return whether the next 2 characters in the input source match the given characters.

fn next_3_are(&self, c1: char, c2: char, c3: char) -> bool

Return whether the next 3 characters in the input source match the given characters.

fn next_is_document_indicator(&self) -> bool

Check whether the next characters correspond to a document indicator.

fn next_is_document_start(&self) -> bool

Check whether the next characters correspond to a start of document.

fn next_is_document_end(&self) -> bool

Check whether the next characters correspond to an end of document.

fn skip_ws_to_eol( &mut self, skip_tabs: SkipTabs, ) -> (usize, Result<SkipTabs, &'static str>)

Skip yaml whitespace at most up to eol. Also skips comments. Advances the input.

Check whether the next characters may be part of a plain scalar.

fn next_is_blank_or_break(&self) -> bool

Check whether the next character is a blank or a break.

fn next_is_blank_or_breakz(&self) -> bool

Check whether the next character is a blank or a breakz.

fn next_is_blank(&self) -> bool

Check whether the next character is a blank.

fn next_is_break(&self) -> bool

Check whether the next character is a break.

fn next_is_breakz(&self) -> bool

Check whether the next character is a breakz.

fn next_is_z(&self) -> bool

Check whether the next character is a z.

fn next_is_flow(&self) -> bool

Check whether the next character is a flow.

fn next_is_digit(&self) -> bool

Check whether the next character is a digit.

fn next_is_alpha(&self) -> bool

Check whether the next character is a letter.

fn skip_while_non_breakz(&mut self) -> usize

Skip characters from the input until a breakz is found.

fn skip_while_blank(&mut self) -> usize

Skip characters from the input while blanks are found.

fn fetch_while_is_alpha(&mut self, out: &mut String) -> usize

Fetch characters from the input while we encounter letters and store them in out.
