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

Implementations

impl<'a> StreamParser<'a>

pub fn new<T: AsRef<Path>>(file_path: T, value: &'a str) -> Self

pub fn file_path(&self) -> &Path

Get the file path containing the current text.

pub fn index(&self) -> usize

Get the current index.

pub fn set_index(&mut self, index: usize)

Set the current index.

pub fn next(&self) -> Result<char>

Returns the next byte without advancing the index.

Errors

Returns an error if EOI is found.

pub fn take_next(&mut self) -> Result<char>

Returns the next byte while advancing the index.

Errors

Returns an error if EOI is found.

pub fn peek(&self, n: usize) -> Result<&'a str>

Peek the next n bytes.

Errors

Returns an error if EOI is found.

pub fn peek_exact(&self, val: &str) -> bool

Returns if the next bytes match the provided value.

If EOI is reached, false is returned.

pub fn peek_early(&self, n: usize, e: usize) -> Result<&'a str>

Peek the next n bytes starting at e bytes from the current index.

Errors

Returns an error if EOI is found.

pub fn peek_early_exact(&self, val: &str, e: usize) -> bool

Returns if the next bytes starting at e from the current index match the provided value.

If EOI is reached, false is returned.

pub fn take(&mut self, n: usize) -> Result<()>

Advance the index of the stream of n bytes.

Errors

Returns an error if EOI is found.

pub fn take_exact(&mut self, val: &str) -> Result<()>

Check if the next characters match the value. If the values match, advance the current index of the length of the value and return true, otherwise return false.

Errors

Returns an error if EOI is found or if the next characters does not match the string given as argument.

pub fn trim(&mut self)

Advance the string so that the index will point to a non-space character.

pub fn is_eoi(&self) -> bool

pub fn get_range(&self, range: Range<usize>) -> Result<&'a str>

Get a range of text in the inner content.

Errors

Returns an error if EOI is found.

pub fn take_while<F: FnMut((usize, char)) -> bool>(&mut self, f: F) -> &'a str

pub fn take_while_peekable<F: FnMut(usize, char, Option<char>) -> bool>( &mut self, f: F, ) -> &'a str

pub fn take_until(&mut self, val: &str) -> Result<&'a str>

Take all the data until val is found.

Returns the data taken.

Errors

Returns an error if EOI is found.

pub fn take_until_index(&mut self, val: &str) -> Result<usize>

Take all the data until val is found.

Returns the index of the first character of val in the data.

Errors

Returns an error if EOI is found.

pub fn take_until_eoi(&mut self) -> &'a str
