Struct riot_wrappers::saul::RegistryEntry

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

Available on riot_module_saul only.

A discovered SAUL registry entry

Implementations

impl RegistryEntry

pub fn nth(pos: usize) -> Option<Self>

Find a registry entry by its index

Wrapper around saul_reg_find_nth.

pub fn all() -> AllRegistryEntries

All registered entries.

Do not expect more from its return type than being impl Iterator<Item = Self>; this will change back to that once type_alias_impl_trait is stable.

pub fn type_(&self) -> Option<Class>

pub fn name(&self) -> Option<&'static str>

pub fn read(&self) -> Result<Phydat, NumericError>

Read a value from the SAUL device

pub fn write(&self, value: Phydat) -> Result<(), NumericError>

Write a value to the SAUL device

Note that the saul_reg_write call does not really pass on the initialized length of the values to the device, but the device returns the used length. If the lengths do not match, the returned length is expressed as an error.
