Struct magnus::value::Id

source ·
#[repr(transparent)]
pub struct Id(_);
Expand description

The internal value of a Ruby symbol.

Implementations§

source§

impl Id

source

pub fn new<T>(name: T) -> Selfwhere T: AsRef<str>,

Create a new Id for name.

Panics

Panics if called from a non-Ruby thread.

Examples
use magnus::value::Id;

let id = Id::new("example");
assert_eq!(id.name().unwrap(), "example");
source

pub fn check(name: &str) -> Option<Self>

Return the Id for name, if one exists.

Panics

Panics if called from a non-Ruby thread.

Examples
use magnus::{value::Id, StaticSymbol};

assert!(Id::check("example").is_none());
StaticSymbol::new("example");
assert!(Id::check("example").is_some());
source

pub fn name(self) -> Result<&'static str, Error>

Return the symbol name associated with this Id as a static string reference.

May error if the name is not valid utf-8.

Examples
use magnus::value::Id;

let id = Id::new("example");
assert_eq!(id.name().unwrap(), "example");
