Struct janetrs::JanetKeyword

#[repr(transparent)]
pub struct JanetKeyword<'data> { /* fields omitted */ }

Janet keyword. Janet being a lisp-like language a keyword is not a especial word of the language, it is a normal string that can be defined by the user.

Implementations

impl JanetKeyword<'_>

pub fn new(name: impl AsRef<[u8]>) -> Self

Create a JanetKeyword with given name.

If the given name is bigger than i32::MAX the generated symbol will have a name trucated to that max size. That’s unrealistic thought.

Examples

use janetrs::JanetKeyword;

let k = JanetKeyword::new("name");

pub const unsafe fn from_raw(raw: *const u8) -> Self

Create a new JanetKeyword with a raw pointer.

Safety

This function do not check if the given raw is NULL or not. Use at your own risk.

pub fn len(&self) -> i32

Returns the length of this JanetKeyword, in bytes, not chars or graphemes. In other words, it may not be what a human considers the length of the string.

Examples

use janetrs::JanetKeyword;

let k = JanetKeyword::new("name");
assert_eq!(k.len(), 4);

pub fn is_empty(&self) -> bool

Returns true if this JanetKeyword has a length of zero, and false otherwise.

Examples

use janetrs::JanetKeyword;

let k = JanetKeyword::new("name");
assert!(!k.is_empty());

pub fn as_bytes(&self) -> &[u8]

Returns a byte slice of the JanetString contents.

Examples

use janetrs::JanetKeyword;

let s = JanetKeyword::new("hello");

assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());

pub const fn as_raw(&self) -> *const u8

Return a raw pointer to the keyword raw structure.

The caller must ensure that the buffer outlives the pointer this function returns, or else it will end up pointing to garbage.
