Struct ijson::string::IString[][src]

#[repr(transparent)]
pub struct IString(_);
Expand description

The IString type is an interned, immutable string, and is where this crate gets its name.

Cloning an IString is cheap, and it can be easily converted from &str or String types. Comparisons between IStrings is a simple pointer comparison.

The memory backing an IString is reference counted, so that unlike many string interning libraries, memory is not leaked as new strings are interned. Interning uses DashSet, an implementation of a concurrent hash-set, allowing many strings to be interned concurrently without becoming a bottleneck.

Given the nature of IString it is better to intern a string once and reuse it, rather than continually convert from &str to IString.

Implementations

Converts a &str to an IString by interning it in the global string cache.

Returns the length (in bytes) of this string.

Returns true if this is the empty string “”.

Obtains a &str from this IString. This is a cheap operation.

Obtains a byte slice from this IString. This is a cheap operation.

Returns the empty string.
