# 1.7.0[−][src]Struct std::ffi::IntoStringError

    pub struct IntoStringError { /* fields omitted */ }

An error indicating invalid UTF-8 when converting a `CString` into a `String`.

`CString` is just a wrapper over a buffer of bytes with a nul terminator; `into_string` performs UTF-8 validation on those bytes and may return this error.

This `struct` is created by the `into_string` method on `CString`. See its documentation for more.

## Methods

###

`impl IntoStringError`

[src]

####

`pub fn into_cstring(self) -> CString`

[src]

Consumes this error, returning original `CString` which generated the error.

####

`pub fn utf8_error(&self) -> Utf8Error`

[src]

Access the underlying UTF-8 error that was the cause of this error.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
