Struct Strong

pub struct Strong<Ctx: Validator> { /* private fields */ }

Strongly typed str

Implementations

impl<Ctx: Validator> Strong<Ctx>

pub fn validate<S: AsRef<str> + ?Sized>(s: &S) -> Result<&Self, Ctx::Err>

Constructs from str.

pub unsafe fn no_validate<S: AsRef<str> + ?Sized>(s: &S) -> &Self

Constructs from str without validation.

Safety

This function allows us to create invalid Strong.

Converts to str.

impl<Ctx: Validator> Strong<Ctx>

pub fn valid(&self) -> Result<&Self, Ctx::Err>

Converts to StrongBuf.
