Struct Provider 

pub struct Provider(/* private fields */);

Implementations

impl Provider

pub fn load(ctx: Option<&LibCtxRef>, name: &str) -> Result<Self, ErrorStack>

Loads a new provider into the specified library context, disabling the fallback providers.

If ctx is None, the provider will be loaded in to the default library context.

This corresponds to OSSL_provider_load.

pub fn try_load( ctx: Option<&LibCtxRef>, name: &str, retain_fallbacks: bool, ) -> Result<Self, ErrorStack>

Loads a new provider into the specified library context, disabling the fallback providers if retain_fallbacks is false and the load succeeds.

If ctx is None, the provider will be loaded into the default library context.

This corresponds to OSSL_provider_try_load.

pub fn set_default_search_path( ctx: Option<&LibCtxRef>, path: &str, ) -> Result<(), ErrorStack>

Specifies the default search path that is to be used for looking for providers in the specified library context. If left unspecified, an environment variable and a fall back default value will be used instead

If ctx is None, the provider will be loaded into the default library context.

This corresponds to OSSL_PROVIDER_set_default_search_path.

Trait Implementations

impl AsRef<ProviderRef> for Provider

fn as_ref(&self) -> &ProviderRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<ProviderRef> for Provider

fn borrow(&self) -> &ProviderRef

Immutably borrows from an owned value.

impl Deref for Provider

type Target = ProviderRef

The resulting type after dereferencing.

fn deref(&self) -> &ProviderRef

Dereferences the value.

impl DerefMut for Provider

fn deref_mut(&mut self) -> &mut ProviderRef

Mutably dereferences the value.

impl Drop for Provider

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for Provider

type CType = OSSL_PROVIDER

The raw C type.

type Ref = ProviderRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut OSSL_PROVIDER) -> Provider

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut OSSL_PROVIDER

Returns a raw pointer to the wrapped value.

impl Send for Provider

impl Sync for Provider

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
