HostWrapperError

Enum HostWrapperError 

Source
#[non_exhaustive]
pub enum HostWrapperError { InvalidParameter(&'static str), NullHostInstance, NullHostData, Panic, DeactivatedPlugin, ErrorFormatError(Error), Error(Box<dyn Error + 'static>), Message(&'static str), }
Expand description

Errors raised by a HostWrapper.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

InvalidParameter(&'static str)

An invalid parameter value was encountered.

The given string may contain more information about which parameter was found to be invalid.

§

NullHostInstance

The raw clap_host pointer was NULL.

§

NullHostData

The raw clap_host.host_data field was NULL.

§

Panic

A wrapped implementation panicked.

§

DeactivatedPlugin

Tried to call a method that requires the plugin to be activated, but it wasn’t.

§

ErrorFormatError(Error)

Encountered an error while trying to format another HostWrapperError

§

Error(Box<dyn Error + 'static>)

A generic, type-erased error.

§

Message(&'static str)

A constant string message to be displayed.

Implementations§

Source§

impl HostWrapperError

Source

pub fn format_cstr(&self) -> Cow<'static, CStr>

Formats this error into either a CStr or CString.

This will handle formatting failures and return an appropriate message in that case, so unlike the Display implementation, this will always return a displayable error message.
