Struct fst::raw::Output [] [src]

pub struct 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]

Create a new output from a u64.

Create a zero output.

Retrieve the value inside this output.

Returns true if this is a zero output.

Returns the prefix of this output and o.

Returns the concatenation of this output and o.

Returns the subtraction of o from this output.

This function panics if self > o.
