Implementations

impl WasiCryptoCommon

pub fn new(store: &Store, ctx: Rc<RefCell<WasiCryptoCtx>>) -> Self

Creates a new WasiCryptoCommon instance.

External values are allocated into the store provided and configuration of the instance itself should be all contained in the cx parameter.

pub fn get_export(&self, name: &str) -> Option<&Func>

Looks up a field called name in this structure, returning it if found.

This is often useful when instantiating a wasmtime instance where name resolution often happens with strings.

pub fn add_to_linker(&self, linker: &mut Linker) -> Result<()>

Adds all instance items to the specified Linker.

pub fn add_to_config(config: &mut Config)

Adds the host functions to the given wasmtime::Config.

Host functions added to the config expect [set_context] to be called.

Host functions will trap if the context is not set in the calling wasmtime::Store.

pub fn add_options_open_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for options_open to a config under a given module and field name.

pub fn add_options_close_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for options_close to a config under a given module and field name.

pub fn add_options_set_to_config(config: &mut Config, module: &str, field: &str)

Add the host function for options_set to a config under a given module and field name.

pub fn add_options_set_u64_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for options_set_u64 to a config under a given module and field name.

pub fn add_options_set_guest_buffer_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for options_set_guest_buffer to a config under a given module and field name.

pub fn add_array_output_len_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for array_output_len to a config under a given module and field name.

pub fn add_array_output_pull_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for array_output_pull to a config under a given module and field name.

pub fn add_secrets_manager_open_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for secrets_manager_open to a config under a given module and field name.

pub fn add_secrets_manager_close_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for secrets_manager_close to a config under a given module and field name.

pub fn add_secrets_manager_invalidate_to_config(
    config: &mut Config,
    module: &str,
    field: &str
)

Add the host function for secrets_manager_invalidate to a config under a given module and field name.

pub fn set_context(
    store: &Store,
    ctx: WasiCryptoCtx
) -> Result<(), WasiCryptoCtx>

Sets the context in the given store.

Context must be set in the store when using [add_to_config] and prior to any host function being called.

If the context is already set in the store, the given context is returned as an error.
