Struct GenServerSpec 

pub struct GenServerSpec {
    pub module_name: String,
    pub state_doc: String,
    pub handle_calls: Vec<(BeamPattern, BeamExpr)>,
    pub handle_casts: Vec<(BeamPattern, BeamExpr)>,
    pub handle_infos: Vec<(BeamPattern, BeamExpr)>,
    pub init_state: BeamExpr,
    pub terminate_body: Option<BeamExpr>,
}

A gen_server behaviour specification.

gen_server is the OTP generic server process behaviour.

handle_casts: Vec<(BeamPattern, BeamExpr)>

Asynchronous cast handlers: (message_pattern, new_state_expr)

handle_infos: Vec<(BeamPattern, BeamExpr)>

Info message handlers: (message_pattern, new_state_expr)

init_state: BeamExpr

Initial state expression

terminate_body: Option<BeamExpr>
