Struct ParamExtValue

pub struct ParamExtValue {
    pub param_id: [u8; 16],
    pub param_value: [u8; 128],
    pub param_type: MavParamExtType,
    pub param_count: u16,
    pub param_index: u16,
}

MAVLink PARAM_EXT_VALUE message.

Minimum supported MAVLink version is MAVLink 2.

Description

Emit the value of a parameter. The inclusion of param_count and param_index in the message allows the recipient to keep track of received parameters and allows them to re-request missing parameters after a loss or timeout.

Encoding/Decoding

Message encoding/decoding are provided by implementing core::convert::TryFrom<Payload> for ParamExtValue (encoding) and [IntoPayload] (decoding) traits. These traits are implemented by Message proc macro.

Fields

param_id: [u8; 16]

MAVLink field param_id.

Parameter id, terminated by NULL if the length is less than 16 human-readable chars and WITHOUT null termination (NULL) byte if the length is exactly 16 chars - applications have to provide 16+1 bytes storage if the ID is stored as string

param_value: [u8; 128]

MAVLink field param_value.

Parameter value

param_type: MavParamExtType

MAVLink field param_type.

Parameter type.

param_count: u16

MAVLink field param_count.

Total number of parameters

param_index: u16

MAVLink field param_index.

Index of this parameter

Implementations

impl ParamExtValue

Returns specification for this message.

pub const fn message_id() -> MessageId

Message ID.

Message CRC_EXTRA.

pub const fn min_supported_mavlink_version() -> MavLinkVersion

Minimum supported MAVLink version for this message.

Trait Implementations

impl Clone for ParamExtValue

fn clone(&self) -> ParamExtValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParamExtValue

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

Formats the value using the given formatter.

impl Default for ParamExtValue

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ParamExtValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ParamExtValue> for Common

fn from(value: ParamExtValue) -> Self

Converts to this type from the input type.

impl IntoPayload for ParamExtValue

fn encode(&self, version: MavLinkVersion) -> Result<Payload, SpecError>

Encodes message into MAVLink payload.

impl MessageSpec for ParamExtValue

fn id(&self) -> MessageId

MAVLink message ID.

fn min_supported_mavlink_version(&self) -> MavLinkVersion

Minimum supported MAVLink protocol version.

fn crc_extra(&self) -> CrcExtra

Message EXTRA_CRC calculated from message XML definition.

impl MessageSpecStatic for ParamExtValue

fn spec() -> MessageInfo

Returns specification for this message.

fn message_id() -> MessageId

Message ID.

fn crc_extra() -> CrcExtra

Message CRC_EXTRA.

fn min_supported_mavlink_version() -> MavLinkVersion

Minimum supported MAVLink version for this message.

impl NamedType for ParamExtValue

fn sid() -> SpectaID

fn named_data_type( type_map: &mut TypeCollection, generics: &[DataType], ) -> NamedDataType

this is equivalent to Type::inline but returns a NamedDataType instead.

fn definition_named_data_type(type_map: &mut TypeCollection) -> NamedDataType

this is equivalent to [Type::definition] but returns a NamedDataType instead.

impl PartialEq for ParamExtValue

fn eq(&self, other: &ParamExtValue) -> 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 Serialize for ParamExtValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&Payload> for ParamExtValue

type Error = SpecError

The type returned in the event of a conversion error.

fn try_from(value: &Payload) -> Result<Self, Self::Error>

Performs the conversion.

impl Type for ParamExtValue

fn inline(type_map: &mut TypeCollection, generics: Generics<'_>) -> DataType

Returns the definition of a type using the provided generics.

fn reference(type_map: &mut TypeCollection, generics: &[DataType]) -> Reference

Generates a datatype corresponding to a reference to this type, as determined by its category. Getting a reference to a type implies that it should belong in the type map (since it has to be referenced from somewhere), so the output of definition will be put into the type map.

impl Flatten for ParamExtValue

impl Message for ParamExtValue

impl StructuralPartialEq for ParamExtValue
