Struct CallbackMethodBinding 

pub struct CallbackMethodBinding {
    pub name: String,
    pub doc: Option<String>,
    pub deprecated: Option<String>,
    pub throws: bool,
    pub params: Vec<ParamBinding>,
    pub ret: Option<Ty>,
    pub abi_params: Vec<AbiParam>,
    pub abi_ret: CType,
}

One method of a callback interface, lowered to its vtable entry.

The consumer implements this; the producer calls it through the vtable. abi_params is the full C slot list of the vtable entry (void* ctx, the parameter slots, the return’s out slots, then {prefix}_error* out_err) and abi_ret its C return type.

Fields

name: String

The method name as written in the IDL; also the vtable field name.

doc: Option<String>

Optional doc comment carried from the IDL.

deprecated: Option<String>

Deprecation message when the method is marked deprecated, else None.

throws: bool

Whether the method may report a positive code of the error domain in scope (Model::error_domain) through its out_err.

params: Vec<ParamBinding>

Input parameters with their lowered slots.

ret: Option<Ty>

The resolved return type (None = void). Any family but iterators and callback interfaces; see lower_callback_return.

abi_params: Vec<AbiParam>

The vtable entry’s C parameter slots: ctx, then every parameter’s slots, then the return’s out slots (out_ptr and out_len for a string, bytes, or buffer return), then out_err.

abi_ret: CType

The vtable entry’s C return type.

Implementations

impl CallbackMethodBinding

pub fn error_strategy(&self) -> ErrorStrategy

The error strategy of this method: ErrorStrategy::Throws when it declares throws: true, otherwise ErrorStrategy::Trap (any failure reaches the producer as -4).
