Struct UserId

Source

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

Expand description

Type-safe wrapper for user identifiers.

This provides compile-time safety to prevent mixing up user IDs with other string types. It’s used in coordination layer functions to ensure type safety when passing user identifiers.

Implementations§

Source §

impl UserId

Source

pub fn new(id: String) -> Result<Self, SessionError>

Creates a new UserId from a string with validation.

§Arguments

id - The user ID string

§Returns

Ok(UserId) - If the ID is valid
Err(SessionError) - If the ID is invalid

§Validation Rules

Must not be empty
Must contain only safe characters (alphanumeric + basic symbols)
Must not contain control characters or dangerous sequences

Source

pub fn as_str(&self) -> &str

Returns the user ID as a string slice.

§Returns

A string slice containing the user ID
