#[repr(transparent)]
pub struct EspError(_);
Expand description

A wrapped esp_err_t to check if an error occurred.

An esp_err_t is returned from most esp-idf APIs as a status code. If it is equal to ESP_OK it means no error occurred.

Implementations

Wrap an esp_err_t, return [Some] if error is not ESP_OK.

Wrap a [NonZeroI32]. Since ESP_OK is 0, this can never fail;

Wrap an esp_err_t, throw a compile time error if error is ESP_OK.

Convert error into a [Result] with Ok(value) if no error occurred.

If error is ESP_OK return [Ok] of value otherwise return [Err] of wrapped error.

Convert error into a [Result] with Ok(()) if not error occurred..

If error equals to ESP_OK return [Ok], otherwise return [Err] with the wrapped esp_err_t.

Panic with a specific error message of the contained esp_err_t.

Get the wrapped esp_err_t.
