Struct ScannerMode

pub struct ScannerMode { /* private fields */ }

A scanner mode that can be used to scan specific parts of the input. The contained data is used to create a scanner mode that can be used to scan the input.

Implementations

impl ScannerMode

pub fn new<P, T>(name: &str, patterns: P, mode_transitions: T) -> Self

where P: IntoIterator<Item = Pattern>, T: IntoIterator<Item = (usize, usize)>,

Creates a new scanner mode with the given name and patterns.

Arguments

• name - The name of the scanner mode.
• patterns - The regular expressions that are valid token types in this mode, bundled with their token type numbers.
• mode_transitions - The transitions between the scanner modes triggered by a token type number. It is a vector of tuples of the token type numbers and the new scanner mode index. The entries should be are sorted by token type number. The scanner mode index is the index of the scanner mode in the scanner mode vector of the scanner and is determined by the order of the insertions of scanner modes into the scanner.

Returns

The new scanner mode.

pub fn name(&self) -> &str

Returns the name of the scanner mode.

Trait Implementations

impl Clone for ScannerMode

fn clone(&self) -> ScannerMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScannerMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScannerMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScannerMode

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

impl Serialize for ScannerMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
