[−][src]Struct fst::raw::Output
An output is a value that is associated with a key in a finite state transducer.
Note that outputs must satisfy an algebra. Namely, it must have an additive
identity and the following binary operations defined: prefix
,
concatenation
and subtraction
. prefix
and concatenation
are
commutative while subtraction
is not. subtraction
is only defined on
pairs of operands where the first operand is greater than or equal to the
second operand.
Currently, output values must be u64
. However, in theory, an output value
can be anything that satisfies the above algebra. Future versions of this
crate may make outputs generic on this algebra.
Methods
impl Output
[src]
pub fn new(v: u64) -> Output
[src]
Create a new output from a u64
.
pub fn zero() -> Output
[src]
Create a zero output.
pub fn value(self) -> u64
[src]
Retrieve the value inside this output.
pub fn is_zero(self) -> bool
[src]
Returns true if this is a zero output.
pub fn prefix(self, o: Output) -> Output
[src]
Returns the prefix of this output and o
.
pub fn cat(self, o: Output) -> Output
[src]
Returns the concatenation of this output and o
.
pub fn sub(self, o: Output) -> Output
[src]
Returns the subtraction of o
from this output.
This function panics if self > o
.
