Struct stm32wb_hci::types::ConnectionIntervalBuilder

pub struct ConnectionIntervalBuilder { /* private fields */ }

Intermediate builder for the ConnectionInterval.

Implementations

impl ConnectionIntervalBuilder

pub fn new() -> ConnectionIntervalBuilder

Initializes a new builder.

pub fn with_range( &mut self, min: Duration, max: Duration ) -> &mut ConnectionIntervalBuilder

Sets the connection interval range.

Errors

There are no errors from this function, but it may cause errors in build if:

• min is greater than max
• Either min or max is less than 7.5 ms or more than 4 seconds.
• max leads to an invalid relative supervision timeout.

pub fn with_latency(&mut self, latency: u16) -> &mut ConnectionIntervalBuilder

Sets the connection latency.

Errors

There are no errors from this function, but it may cause errors in build if:

• latency is 500 or greater.
• latency leads to an invalid relative supervision timeout.

pub fn with_supervision_timeout( &mut self, timeout: Duration ) -> &mut ConnectionIntervalBuilder

Sets the supervision timeout.

Errors

There are no errors from this function, but it may cause errors in build if:

• timeout less than 100 ms or greater than 32 seconds
• timeout results in an invalid relative supervision timeout.

pub fn build(&self) -> Result<ConnectionInterval, ConnectionIntervalError>

Builds the connection interval if all parameters are valid.

Errors

• Incomplete if any of with_range, with_latency, or with_supervision_timeout have not been called.
• IntervalTooShort if the minimum range value is less than 7.5 ms.
• IntervalTooLong if the maximum range value is greater than 4 seconds.
• IntervalInverted if the minimum range value is greater than the maximum.
• BadConnectionLatency if the connection latency is 500 or more.
• SupervisionTimeoutTooShort if the supervision timeout is less than 100 ms, or if it is less than the computed minimum: (1 + latency) * interval max * 2.
• SupervisionTimeoutTooLong if the supervision timeout is more than 32 seconds.
• ImpossibleSupervisionTimeout if the computed minimum supervision timeout ((1 + latency) * interval max * 2) is 32 seconds or more.

Trait Implementations

impl Default for ConnectionIntervalBuilder

fn default() -> ConnectionIntervalBuilder

Returns the “default value” for a type.
