Struct password_hash::Ident

pub struct Ident<'a>(_);

Algorithm or parameter identifier.

This type encompasses both the “function symbolic name” and “parameter name” use cases as described in the PHC string format specification.

Constraints

• ASCII-encoded string consisting of the characters [a-z0-9-] (lowercase letters, digits, and the minus sign)
• Minimum length: 1 ASCII character (i.e. 1-byte)
• Maximum length: 32 ASCII characters (i.e. 32-bytes)

Implementations

impl<'a> Ident<'a>

pub const fn new(s: &'a str) -> Self

Parse an Ident from a string.

Panics

Must conform to the contraints given in the type-level documentation, or else it will panic.

This method is intended for use in a const context where instead of panicking it will cause a compile error.

For fallible non-panicking parsing of an Ident, use the TryFrom impl on this type instead.

pub fn as_str(&self) -> &'a str

Borrow this ident as a str
