Enum StateLoadError 

#[non_exhaustive]
pub enum StateLoadError {
    Malformed(&'static str),
    Other(String),
}

Reason a crate::Plugin::load_state / truce_plugin::PluginLogic::load_state implementation failed to interpret the host-supplied extra-state blob. Format wrappers receive this on the audio-thread apply path and log it; hosts that surface a non-success code to the DAW (e.g. CLAP state_load returning false) read the variant via that path.

Malformed is the typical case: the blob’s framing or content doesn’t match what save_state would emit (version skew between older session files and newer plugin builds is the canonical example). Other carries a free-form message for plugin-specific failures that don’t fit the malformed-bytes shape.

Variants (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.

Malformed(&'static str)

State blob is too short, mis-framed, or otherwise unparseable.

Other(String)

Plugin-specific failure with a free-form message.

Trait Implementations

impl Debug for StateLoadError

impl Error for StateLoadError

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.
