Struct strong::StrongBuf

pub struct StrongBuf<Ctx: Validator> { /* fields omitted */ }

Strongly typed String

Implementations

impl<Ctx: Validator> StrongBuf<Ctx>

pub fn validate(s: String) -> Result<Self, Ctx::Err>

Constructs from String.

pub unsafe fn no_validate(s: String) -> Self

Constructs from String without validation.

Safety

This function allows us to create invalid StrongBuf.

pub fn into_string(self) -> String

Converts to String.

pub fn as_strong(&self) -> &Strong<Ctx>

impl<Ctx: Validator> StrongBuf<Ctx>

pub unsafe fn from_utf8_unchecked(bytes: Vec<u8>) -> Self

Constructs from Vec<u8> without validation.

Safety

This function allows us to create invalid StrongBuf, and it may not even be a valid utf-8.

Methods from Deref<Target = Strong<Ctx>>

pub fn as_str(&self) -> &str
