Expand description

Helper trait to easily convert various Result types into [RpcResult]

Required Methods§

Source

fn map_rpc_err<'a, F, M>(self, op: F) -> Result<Ok, ErrorObject<'static>>
where F: FnOnce(Err) -> (i32, M, Option<&'a [u8]>), M: Into<String>,

Converts this type into an [RpcResult]

Source

fn map_internal_err<F, M>(self, op: F) -> Result<Ok, ErrorObject<'static>>
where F: FnOnce(Err) -> M, M: Into<String>,

Converts this type into an [RpcResult] with the [jsonrpsee_types::error::INTERNAL_ERROR_CODE] and the given message.

Source

fn map_internal_err_with_data<'a, F, M>( self, op: F, ) -> Result<Ok, ErrorObject<'static>>
where F: FnOnce(Err) -> (M, &'a [u8]), M: Into<String>,

Converts this type into an [RpcResult] with the [jsonrpsee_types::error::INTERNAL_ERROR_CODE] and given message and data.

Source

fn with_message(self, msg: &str) -> Result<Ok, ErrorObject<'static>>

Adds a message to the error variant and returns an internal Error.

This is shorthand for Self::map_internal_err(|err| format!("{msg}: {err}")).

Provided Methods§

Source

fn to_rpc_result(self) -> Result<Ok, ErrorObject<'static>>
where Err: Display,

Converts result to [RpcResult] by converting error variant to [jsonrpsee_types::error::ErrorObject]

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
