Implementations§
source§impl EspError
impl EspError
sourcepub const fn from_non_zero(error: NonZeroI32) -> Self
pub const fn from_non_zero(error: NonZeroI32) -> Self
Wrap a [NonZeroI32
]. Since ESP_OK
is 0, this can never fail;
sourcepub const fn from_infallible<const E: esp_err_t>() -> Self
pub const fn from_infallible<const E: esp_err_t>() -> Self
sourcepub fn check_and_return<T>(error: esp_err_t, value: T) -> Result<T, Self>
pub fn check_and_return<T>(error: esp_err_t, value: T) -> Result<T, Self>
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
.
