Enum Error

pub enum Error {
    DescriptorTooLong,
    DescriptorBufferTooLong,
    ValueBufferTooLong,
    TooManyHandlesToRead,
}

Potential errors from parameter validation.

Before some commands are sent to the controller, the parameters are validated. This type enumerates the potential validation errors. Must be specialized on the types of communication errors.

Variants

DescriptorTooLong

For the Add Characteristic Descriptor command: the descriptor value is longer than the maximum descriptor value length.

DescriptorBufferTooLong

For the Add Characteristic Descriptor command: the descriptor value maximum length is so large that the serialized structure may be more than 255 bytes. The maximum size is 227.

ValueBufferTooLong

For the Update Characteristir Value command: the length of the characteristic value is so large that the serialized structure would be more than 255 bytes. The maximum size is 249.

TooManyHandlesToRead

For the Read Multiple Characteristic Values command: the number of handles would cause the serialized command to be more than 255 bytes. The maximum length is 126 handles.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl StructuralPartialEq for Error
