Enum cmdmat::Decision

pub enum Decision<D> {
    Accept(usize),
    Deny(D),
}

A decision contains information about token consumption by the decider

If the decider has accepted the tokens, it will return an Accept(usize), if it failed to parse interpret the tokens, it will return a deny value.

Variants

Accept(usize)

Accept any number of inputs

Deny(D)

Deny the input

Trait Implementations

impl<D: PartialEq> PartialEq<Decision<D>> for Decision<D>

fn eq(&self, other: &Decision<D>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Decision<D>) -> bool

This method tests for !=.

impl<D: Debug> Debug for Decision<D>

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

Formats the value using the given formatter.

impl<D> Try for Decision<D>

type Ok = usize

🔬 This is a nightly-only experimental API. (try_trait)

The type of this value when viewed as successful.

type Error = D

🔬 This is a nightly-only experimental API. (try_trait)

The type of this value when viewed as failed.

fn into_result(self) -> Result<Self::Ok, Self::Error>

🔬 This is a nightly-only experimental API. (try_trait)

Applies the "?" operator. A return of Ok(t) means that the execution should continue normally, and the result of ? is the value t. A return of Err(e) means that execution should branch to the innermost enclosing catch, or return from the function.

fn from_error(v: Self::Error) -> Self

🔬 This is a nightly-only experimental API. (try_trait)

Wrap an error value to construct the composite result. For example, Result::Err(x) and Result::from_error(x) are equivalent.

fn from_ok(v: Self::Ok) -> Self

🔬 This is a nightly-only experimental API. (try_trait)

Wrap an OK value to construct the composite result. For example, Result::Ok(x) and Result::from_ok(x) are equivalent.
