Struct regex_automata::nfa::thompson::Transition
source · pub struct Transition {
pub start: u8,
pub end: u8,
pub next: StateID,
}
Expand description
A single transition to another state.
This transition may only be followed if the current byte in the haystack falls in the inclusive range of bytes specified.
Fields§
§start: u8
The inclusive start of the byte range.
end: u8
The inclusive end of the byte range.
next: StateID
The identifier of the state to transition to.
Implementations§
source§impl Transition
impl Transition
sourcepub fn matches(&self, haystack: &[u8], at: usize) -> bool
pub fn matches(&self, haystack: &[u8], at: usize) -> bool
Returns true if the position at
in haystack
falls in this
transition’s range of bytes.
If at >= haystack.len()
, then this returns false
.
sourcepub fn matches_unit(&self, unit: Unit) -> bool
pub fn matches_unit(&self, unit: Unit) -> bool
Returns true if the given alphabet unit falls in this transition’s
range of bytes. If the given unit is EOI
, then
this returns false
.
sourcepub fn matches_byte(&self, byte: u8) -> bool
pub fn matches_byte(&self, byte: u8) -> bool
Returns true if the given byte falls in this transition’s range of bytes.
