Struct ParamExtRequestRead 

pub struct ParamExtRequestRead {
    pub target_system: u8,
    pub target_component: u8,
    pub param_id: [u8; 16],
    pub param_index: i16,
}

MAVLink PARAM_EXT_REQUEST_READ message.

The minimum supported MAVLink version is MAVLink 2.

Description

Request to read the value of a parameter with either the param_id string id or param_index. PARAM_EXT_VALUE should be emitted in response.

Encoding/Decoding

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

Fields

target_system: u8

MAVLink field target_system.

System ID

target_component: u8

MAVLink field target_component.

Component ID

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_index: i16

MAVLink field param_index.

Parameter index. Set to -1 to use the Parameter ID field as identifier (else param_id will be ignored)

Implementations

impl ParamExtRequestRead

pub const ID: MessageId = 320u32

MavLink message ID.

pub const fn spec() -> MessageInfo

Returns specification for this message.

pub const fn message_id() -> MessageId

Message ID.

pub const fn crc_extra() -> CrcExtra

Message CRC_EXTRA.

pub const fn min_supported_mavlink_version() -> MavLinkVersion

Minimum supported MAVLink version for this message.

Trait Implementations

impl Clone for ParamExtRequestRead

fn clone(&self) -> ParamExtRequestRead

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamExtRequestRead

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

Formats the value using the given formatter.

impl Default for ParamExtRequestRead

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ParamExtRequestRead

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ParamExtRequestRead> for Common

fn from(value: ParamExtRequestRead) -> Self

Converts to this type from the input type.

impl IntoPayload for ParamExtRequestRead

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

Encodes message into MAVLink payload.

impl MessageSpec for ParamExtRequestRead

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 ParamExtRequestRead

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 ParamExtRequestRead

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 ParamExtRequestRead

fn eq(&self, other: &ParamExtRequestRead) -> 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 ParamExtRequestRead

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 ParamExtRequestRead

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 ParamExtRequestRead

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 ParamExtRequestRead

impl Message for ParamExtRequestRead

impl StructuralPartialEq for ParamExtRequestRead
