Struct Uuid16

#[repr(C)]
pub struct Uuid16 {
    u: ble_uuid_t,
    value: [u8; 2],
}

Available on riot_module_nimble_host only.

A wrapper around ble_uuid{16,32,128}_t.

The bit length is stored in this type (as opposed to only being known through the type), as that allows getting a full ble_uuid_any_t as a pointer out of a reference to a UuidX. The stored bit length is an invariant (as it’s needed for the …_any_t to be usable).

(Internally, this is emulated and a ble_uuid128_t-like structure is used to ease and because the author sees no reason to treat shorter numerics as scalars rather than arrays.)

Fields

u: ble_uuid_t

value: [u8; 2]

Implementations

impl Uuid16

pub const fn value(&self) -> &[u8; 2]

Trait Implementations

impl FromStr for Uuid16

type Err = UuidParseError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, UuidParseError>

Parses a string s to return a value of this type.

impl<'a> Into<*const ble_uuid_t> for &'a Uuid16

Useful for building values for things like ble_gatt_svc_def that take a pointer to a ble_uuid_t rather than to a ble_uuid_any_t, probably to simplify casting in C.

fn into(self) -> *const ble_uuid_t

Converts this type into the (usually inferred) input type.

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.
