Transforms common types to a char for basic token parsing
Required Methods§
Sourcefn is_alpha(self) -> bool
fn is_alpha(self) -> bool
Tests that self is an alphabetic character
Warning: for &str it recognizes alphabetic
characters outside of the 52 ASCII letters
Sourcefn is_alphanum(self) -> bool
fn is_alphanum(self) -> bool
Tests that self is an alphabetic character or a decimal digit
Sourcefn is_dec_digit(self) -> bool
fn is_dec_digit(self) -> bool
Tests that self is a decimal digit
Sourcefn is_hex_digit(self) -> bool
fn is_hex_digit(self) -> bool
Tests that self is an hex digit
Sourcefn is_oct_digit(self) -> bool
fn is_oct_digit(self) -> bool
Tests that self is an octal digit
Sourcefn is_bin_digit(self) -> bool
fn is_bin_digit(self) -> bool
Tests that self is a binary digit
Sourcefn is_newline(self) -> bool
fn is_newline(self) -> bool
Tests if byte is ASCII newline: \n
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
