1.0.0[−][src]Struct std::num::ParseIntError
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.
Methods
impl ParseIntError
[src]
pub fn kind(&self) -> &IntErrorKind
[src]
🔬 This is a nightly-only experimental API. (int_error_matching
#22639)
it can be useful to match errors when making error messages for integer parsing
Outputs the detailed cause of parsing an integer failing.
