Implementations

impl RoleParam

pub fn validate(&self) -> Result<(), RoleValidationError>

Validate role parameter for safety constraints.

pub fn validate_with_index( &self, index: &RoleIndex, ) -> Result<(), RoleValidationError>

Validate role parameter in combination with an index.

pub fn safe_static(count: u32) -> Result<RoleParam, RoleValidationError>

Create a safe static role parameter.

Trait Implementations

impl Clone for RoleParam

fn clone(&self) -> RoleParam

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoleParam

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for RoleParam

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for RoleParam

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RoleParam

fn eq(&self, other: &RoleParam) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
