Struct strong::Strong

#[repr(transparent)]pub struct Strong<Ctx: Validator> { /* fields omitted */ }

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.

impl<Ctx: Validator> Strong<Ctx>

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

Re-validates self

pub fn to_strong_buf(&self) -> StrongBuf<Ctx>

Converts to StrongBuf.

pub fn count_chars(&self) -> usize

pub fn map<F>(&self, f: F) -> Result<&Strong<Ctx>, Ctx::Err> where
    F: FnOnce(&str) -> &str,

pub fn trim(&self) -> Result<&Strong<Ctx>, Ctx::Err>
