Enum ParamConstraint 

pub enum ParamConstraint {
    None,
    Int,
    Uuid,
    Alpha,
    Slug,
    Custom(Regex),
}

Parameter constraints for validation

Variants

None

No constraint - any non-empty string

Int

Must be a valid integer

Uuid

Must be a valid UUID

Alpha

Must contain only alphabetic characters

Slug

Must be a valid slug (alphanumeric + hyphens/underscores)

Custom(Regex)

Custom regex pattern

Implementations

impl ParamConstraint

pub fn from_str(s: &str) -> Result<Self, RoutePatternError>

Parse constraint from string (e.g., “int”, “uuid”, “alpha”)

pub fn validate(&self, value: &str) -> bool

Validate a parameter value against this constraint

Trait Implementations

impl Clone for ParamConstraint

fn clone(&self) -> ParamConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamConstraint

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

Formats the value using the given formatter.

impl PartialEq for ParamConstraint

fn eq(&self, other: &Self) -> 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.
