Struct rune::macros::Storage

pub struct Storage { /* fields omitted */ }

Storage for synthetic language items.

Implementations

impl Storage

pub fn insert_number<N>(&self, number: N) -> usize where
    Number: From<N>, 

Construct a new number.

The number will be stored in this storage, and will be synthetic (rather than from the source).

pub fn insert_str(&self, string: &str) -> usize

Insert the given text into storage and return its id.

This will reuse old storage slots that already contains the given string.

pub fn insert_string(&self, string: String) -> usize

Insert the given owned string into storage and return its id.

This will reuse old storage slots that already contains the given string.

pub fn insert_byte_string(&self, bytes: &[u8]) -> usize

Insert the given text into storage and return its id.

This will reuse old storage slots that already contains the given byte string.

pub fn with_byte_string<F, O>(&self, id: usize, with: F) -> Option<O> where
    F: FnOnce(&[u8]) -> O, 

Get the content of the byte string with the specified id and apply the given operation over it.

pub fn get_string(&self, id: usize) -> Option<String>

Get the content of the string with the specified id.

pub fn with_string<F, O>(&self, id: usize, with: F) -> Option<O> where
    F: FnOnce(&str) -> O, 

Get the content of the string with the specified id and apply the given operation over it.

pub fn get_byte_string(&self, id: usize) -> Option<Vec<u8>>

Get the content of the byte string with the specified id.

pub fn get_number(&self, id: usize) -> Option<Number>

Get the content of the number with the specified id.

pub fn with_number<F, O>(&self, id: usize, with: F) -> Option<O> where
    F: FnOnce(&Number) -> O, 

Get the content of the number with the specified id and apply the given operation over it.

Trait Implementations
