std::num::ParseIntError - Rust
Description: API documentation for the Rust `ParseIntError` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, ParseIntError

# Struct std::num::ParseIntError 1.0.0[−][src]

    pub struct ParseIntError { /* fields omitted */ }

An error which can be returned when parsing an integer.

This error is used as the error type for the `from_str_radix()` functions on the primitive integer types, such as `i8::from_str_radix`.

# Potential causes

Among other causes, `ParseIntError` can be thrown because of leading or trailing whitespace in the string e.g. when it is obtained from the standard input. Using the `str.trim()` method ensures that no whitespace remains before parsing.

## 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`)
