Whitespace

Struct Whitespace 

Source
pub struct Whitespace { /* private fields */ }
Expand description

A bitmask representing the characters that make up a Kind::Whitespace token.

A Token with Kind::Whitespace will store this data internal to the token. Using Token::whitespace_style() will return this bitmask, depending on what characters make up the whitespace token. By default the Lexer will produce combine multiple whitespaces into a single Token, so it is possible that Token::whitespace_style() could contain all of the available bits here. With Feature::SeparateWhitespace the Lexer will produce discrete tokens each which can only have one of the available bits in this bitmask.

use css_lexer::*;
let mut lexer = Lexer::new(&EmptyAtomSet::ATOMS, "\n\t");
{
	// This token will be collapsed Whitespace.
	let token = lexer.advance();
	assert_eq!(token, Kind::Whitespace);
	// The Whitespace is comprised of many bits:
	assert_eq!(token, Whitespace::Newline | Whitespace::Tab);
}

Implementations§

Source§

impl Whitespace

Source

pub const Space: Whitespace

The whitespace token contains at least 1 Space ( ) character.

Source

pub const Tab: Whitespace

The whitespace token contains at least 1 Tab (\t) character.

Source

pub const Newline: Whitespace

The whitespace token contains at least 1 Newline (\n) or newline-adjacent (\r, \r\n, \u{c}) character.

Source

pub const fn bits(&self) -> u8

Returns the underlying bits of the bitmask.

Source

pub const fn all_bits() -> Whitespace

Returns a bitmask that contains all values.

This will include bits that do not have any flags. Use ::all_flags() if you only want to use flags.

Source

pub const fn all_flags() -> Whitespace

Returns a bitmask that contains all flags.

Source

pub const fn is_all_bits(&self) -> bool

Returns true if the bitmask contains all values.

This will check for bits == !0, use .is_all_flags() if you only want to check for all flags

Source

pub const fn is_all_flags(&self) -> bool

Returns true if the bitmask contains all flags.

This will fail if any unused bit is set, consider using .truncate() first.

Source

pub const fn all() -> Whitespace

👎Deprecated: Please use the ::all_bits() constructor

Returns a bitmask that contains all values.

This will include bits that do not have any flags. Use ::all_flags() if you only want to use flags.

Source

pub const fn is_all(&self) -> bool

👎Deprecated: Please use the .is_all_bits() method

Returns true if the bitmask contains all values.

This will check for bits == !0, use .is_all_flags() if you only want to check for all flags

Source

pub const fn full() -> Whitespace

👎Deprecated: Please use the ::all_flags() constructor

Returns a bitmask that contains all flags.

Source

pub const fn is_full(&self) -> bool

👎Deprecated: Please use the .is_all_flags() method

Returns true if the bitmask contains all flags.

This will fail if any unused bit is set, consider using .truncate() first.

Source

pub const fn none() -> Whitespace

Returns a bitmask that does not contain any values.

Source

pub const fn is_none(&self) -> bool

Returns true if the bitmask does not contain any values.

Source

pub const fn truncate(&self) -> Whitespace

Returns a bitmask that only has bits corresponding to flags

Source

pub const fn intersects(&self, other: Whitespace) -> bool

Returns true if self intersects with any value in other, or if other does not contain any values.

This is equivalent to (self & other) != 0 || other == 0.

Source

pub const fn contains(&self, other: Whitespace) -> bool

Returns true if self contains all values of other.

This is equivalent to (self & other) == other.

Source

pub const fn not(self) -> Whitespace

Returns the bitwise NOT of the bitmask.

Source

pub const fn and(self, other: Whitespace) -> Whitespace

Returns the bitwise AND of the bitmask.

Source

pub const fn or(self, other: Whitespace) -> Whitespace

Returns the bitwise OR of the bitmask.

Source

pub const fn xor(self, other: Whitespace) -> Whitespace

Returns the bitwise XOR of the bitmask.
