Enum cargo_metadata::Message

#[non_exhaustive]
pub enum Message {
    CompilerArtifact(Artifact),
    CompilerMessage(CompilerMessage),
    BuildScriptExecuted(BuildScript),
    BuildFinished(BuildFinished),
    TextLine(String),
}

A cargo message

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CompilerArtifact(Artifact)

The compiler generated an artifact

CompilerMessage(CompilerMessage)

The compiler wants to display a message

BuildScriptExecuted(BuildScript)

A build script successfully executed.

BuildFinished(BuildFinished)

The build has finished.

This is emitted at the end of the build as the last message. Added in Rust 1.44.

TextLine(String)

A line of text which isn’t a cargo or compiler message. Line separator is not included

Implementations

impl Message

pub fn parse_stream<R: Read>(input: R) -> MessageIter<R>

Creates an iterator of Message from a Read outputting a stream of JSON messages. For usage information, look at the top-level documentation.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Message

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<Message> for Message

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Message

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

Serialize this value into the given Serde serializer.

impl Eq for Message

impl StructuralEq for Message

impl StructuralPartialEq for Message
