Struct MessageStructure 

pub struct MessageStructure {
    pub fields: Vec<MessageFieldInfo>,
    pub size: usize,
    pub namespace: String,
    pub type_name: String,
}

A description of the structure of a message.

Namely, the list of fields and their types.

Fields

fields: Vec<MessageFieldInfo>

The set of fields in the message, ordered by their offset in the message.

A Vec is easier to handle and faster than a HashMap for typical numbers of message fields. If you need a HashMap, simply create your own from this Vec.

size: usize

The size of this structure in bytes.

namespace: String

The namespace of this type. This is something like geometry_msgs__msg.

type_name: String

The name of this type. This does not contain the package name.

Implementations

impl MessageStructure

pub fn get_field_info(&self, field_name: &str) -> Option<&MessageFieldInfo>

Gets the field info corresponding to the specified field name, if any.

Trait Implementations

impl Clone for MessageStructure

fn clone(&self) -> MessageStructure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageStructure

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

Formats the value using the given formatter.

impl PartialEq for MessageStructure

fn eq(&self, other: &MessageStructure) -> 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.
