Implementations

impl ParamRequirement

pub const fn single() -> ParamRequirement

pub const fn exhaustive() -> ParamRequirement

Makes the requirements exhaustive i.e. the parameter set requires that the function is called with no arguments than parameters

pub const fn optional() -> ParamRequirement

Returns the requirements for a single optional parameter

pub const fn any() -> ParamRequirement

Returns the requirements for a any number of parameters

pub const fn none() -> ParamRequirement

Returns the requirements for no parameters

pub const fn combine(self, other: ParamRequirement) -> ParamRequirement

Combine to requirements into one which covers both.

pub fn min(&self) -> usize

Returns the minimum number of arguments for this requirement

pub fn max(&self) -> usize

Returns the maximum number of arguments for this requirement

pub fn is_exhaustive(&self) -> bool
