Enum CallError 

pub enum CallError {
    UnsupportedVerb,
    InvalidArgs,
    Internal,
    Unknown(u32),
    ShortCommand {
        found: usize,
        expected: usize,
    },
}

What one call to a plugin came back with.

Variants

UnsupportedVerb

The plugin does not do that verb.

Not a failure of the run: for exec the host may still run the user’s command verbatim, and that decision belongs to the engine.

InvalidArgs

The plugin thinks the call was malformed.

Internal

The plugin failed internally, including a panic it contained itself.

Unknown(u32)

A code this host does not know.

Kept as it came: the rule is that an unknown code is treated like CallError::Internal, but a host that wants to log the number can.

ShortCommand

The plugin answered success but filled in a pmpx_plugin_abi::PmpxCommand smaller than this host knows how to read.

Fields

found: usize

The size the plugin declared.

expected: usize

The size this host needs.

Implementations

impl CallError

pub fn code(&self) -> Option<u32>

The code the plugin answered with, for a message that wants to show it.

Trait Implementations

impl Clone for CallError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CallError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CallError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for CallError

impl Error for CallError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for CallError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
