Struct ChallengeType 

pub struct ChallengeType(/* private fields */);

Type-safe wrapper for WebAuthn challenge types.

This provides compile-time safety to prevent mixing up challenge types with other string types. Challenge types identify the kind of WebAuthn operation (registration, authentication) and are used as cache prefixes for storing challenge data.

Implementations

impl ChallengeType

pub fn new(challenge_type: String) -> Result<Self, PasskeyError>

Creates a new ChallengeType from a string with validation.

This constructor validates the challenge type to ensure it meets requirements for cache operations and WebAuthn flow identification.

Arguments

• challenge_type - The challenge type string

Returns

• Ok(ChallengeType) - If the challenge type is valid
• Err(PasskeyError) - If the challenge type is invalid

Validation Rules

• Must not be empty
• Must contain only alphanumeric characters and underscores
• Must be reasonable length

pub fn as_str(&self) -> &str

Returns the challenge type as a string slice.

Returns

• A string slice containing the challenge type

pub fn registration() -> Self

Creates a registration challenge type.

Returns

• A ChallengeType for registration operations

pub fn authentication() -> Self

Creates an authentication challenge type.

Returns

• A ChallengeType for authentication operations

Trait Implementations

impl Clone for ChallengeType

fn clone(&self) -> ChallengeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChallengeType

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

Formats the value using the given formatter.

impl PartialEq for ChallengeType

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