Enum StructError 

pub enum StructError {
    NoSuchNode(String),
    Invalid(String),
    TooBig(usize, usize),
    ModTooDeep(usize),
    OutOfDomain(f64, String),
}

Why a structural edit was rejected.

Variants

NoSuchNode(String)

No node at that key.

Invalid(String)

The operation does not apply to this node kind.

TooBig(usize, usize)

The edit would exceed the size/depth ceilings.

ModTooDeep(usize)

The edit would stack more CV processors on one cable than the realtime voice is willing to carry.

OutOfDomain(f64, String)

A continuous site would be seated outside its declared range (crate::PARAM_DOMAIN).

Reported by validate_tree, the predicate. It is deliberately not how apply_struct_op and the whole-tree replace behave — see PatchTree::clamp_domains for why a domain fault is repaired rather than refused.

Trait Implementations

impl Debug for StructError

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

Formats the value using the given formatter.

impl Display for StructError

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

Formats the value using the given formatter.

impl Error for StructError

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.
