# 1.0.0[−][src]Struct std::io::StdinLock

    pub struct StdinLock<'a> { /* fields omitted */ }

A locked reference to the `Stdin` handle.

This handle implements both the `Read` and `BufRead` traits, and is constructed via the `Stdin::lock` method.

## 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`)
