Struct MaybeInvalid 

pub struct MaybeInvalid<T>(/* private fields */);

Available on crate feature server only.

Extract a String or FastStr without checking.

This type can extract a String or FastStr like String::from_utf8_unchecked or FastStr::from_vec_u8_unchecked. Note that extracting them is unsafe and users should assume that the value is valid.

Implementations

impl MaybeInvalid<String>

pub unsafe fn assume_valid(self) -> String

Assume the String is valid and extract it without checking.

Safety

It is up to the caller to guarantee that the value really is valid. Using this when the content is invalid causes immediate undefined behavior.

impl MaybeInvalid<FastStr>

pub unsafe fn assume_valid(self) -> FastStr

Assume the FastStr is valid and extract it without checking.

Safety

It is up to the caller to guarantee that the value really is valid. Using this when the content is invalid causes immediate undefined behavior.

Trait Implementations

impl<T: Clone> Clone for MaybeInvalid<T>

fn clone(&self) -> MaybeInvalid<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for MaybeInvalid<T>
