Struct ros_message::Srv

pub struct Srv { /* private fields */ }

A ROS service parsed from a srv file.

Implementations

impl Srv

pub fn new(path: MessagePath, source: impl Into<String>) -> Result<Srv>

Create a service from a passed in path and source.

Errors

Returns an error if there is an error parsing the service source.

Examples

let service = Srv::new(
    "foo/Bar".try_into()?,
    r#"# a comment that is ignored
    Header header
    uint32 a
    byte[16] b
    geometry_msgs/Point[] point
    uint32 FOO=5
    string SOME_TEXT=this is # some text, don't be fooled by the hash
---
    uint32 a
    geometry_msgs/Point[] point
    uint32 FOO=6
    "#,
)?;

assert_eq!(service.path(), &"foo/Bar".try_into()?);
assert_eq!(service.request().fields().len(), 6);
assert_eq!(service.response().fields().len(), 3);

pub fn path(&self) -> &MessagePath

Returns the path of the service.

pub fn source(&self) -> &str

Returns the original source.

pub fn request(&self) -> &Msg

Returns the request message.

pub fn response(&self) -> &Msg

Returns the response message.

Trait Implementations

impl Clone for Srv

fn clone(&self) -> Srv

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Srv

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Srv

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Srv

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

Formats the value using the given formatter.

impl Hash for Srv

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Srv

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
