Struct Cache

pub struct Cache { /* private fields */ }

Available on crate feature cache only.

Global configuration for how the cache is managed

Implementations

impl Cache

pub fn new(config: CacheConfig) -> Result<Cache, Error>

Builds a Cache from the configuration and spawns the cache worker.

If you want to load the cache configuration from a file, use CacheConfig::from_file. You can call CacheConfig::new for the default configuration.

Errors

Returns an error if the configuration is invalid.

pub fn from_file(path: Option<&Path>) -> Result<Cache, Error>

Loads cache configuration specified at path.

This method will read the file specified by path on the filesystem and attempt to load cache configuration from it. This method can also fail due to I/O errors, misconfiguration, syntax errors, etc. For expected syntax in the configuration file see the documentation online.

Passing in None loads cache configuration from the system default path. This is located, for example, on Unix at $HOME/.config/wasmtime/config.toml and is typically created with the wasmtime config new command.

Errors

This method can fail due to any error that happens when loading the file pointed to by path and attempting to load the cache configuration.
