Struct SignatureHelp 

pub struct SignatureHelp {
    pub active_parameter: Option<Uinteger>,
    pub active_signature: Option<Uinteger>,
    pub signatures: Vec<SignatureInformation>,
}

Signature help represents the signature of something callable. There can be multiple signature but only one active and only one active parameter.

Fields

active_parameter: Option<Uinteger>

The active parameter of the active signature. If omitted or the value lies outside the range of signatures[activeSignature].parameters defaults to 0 if the active signature has parameters. If the active signature has no parameters it is ignored. In future version of the protocol this property might become mandatory to better express the active parameter if the active signature does have any.

active_signature: Option<Uinteger>

The active signature. If omitted or the value lies outside the range of signatures the value defaults to zero or is ignored if the SignatureHelp has no signatures.

Whenever possible implementors should make an active decision about the active signature and shouldn’t rely on a default value.

In future version of the protocol this property might become mandatory to better express this.

signatures: Vec<SignatureInformation>

One or more signatures. If no signatures are available the signature help request should return null.

Trait Implementations

impl Clone for SignatureHelp

fn clone(&self) -> SignatureHelp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureHelp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SignatureHelp

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SignatureHelp

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
