Struct ViewFunctionInfo 

pub struct ViewFunctionInfo<'info, TypeId: Clone> {
    pub query_id: [u8; 32],
    pub inputs: Cow<'info, [ViewFunctionInput<'info, TypeId>]>,
    pub output_id: TypeId,
}

Information about a View Function.

Fields

query_id: [u8; 32]

The query Id to use to call the view function.

inputs: Cow<'info, [ViewFunctionInput<'info, TypeId>]>

Inputs to the runtime API.

output_id: TypeId

The output type returned from the runtime API.

Implementations

impl<'info, TypeId: Clone> ViewFunctionInfo<'info, TypeId>

pub fn into_owned(self) -> ViewFunctionInfo<'static, TypeId>

Take ownership of this info, turning any lifetimes to 'static.

pub fn map_ids<NewTypeId: Clone, E, F: FnMut(TypeId) -> Result<NewTypeId, E>>( self, f: F, ) -> Result<ViewFunctionInfo<'static, NewTypeId>, E>

Map the type IDs in this ViewFunctionInfo, returning a new one or bailing early with an error if something goes wrong. This also takes ownership of the ViewFunctionInfo, turning the lifetime to static.

Trait Implementations

impl<'info, TypeId: Clone + Clone> Clone for ViewFunctionInfo<'info, TypeId>

fn clone(&self) -> ViewFunctionInfo<'info, TypeId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'info, TypeId: Debug + Clone> Debug for ViewFunctionInfo<'info, TypeId>

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

Formats the value using the given formatter.

impl<'info, TypeId: PartialEq + Clone> PartialEq for ViewFunctionInfo<'info, TypeId>

fn eq(&self, other: &ViewFunctionInfo<'info, TypeId>) -> 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.
