Enum SchemaLowerError 

pub enum SchemaLowerError {
    UnsupportedFieldType {
        field: String,
        ty: String,
    },
    UntypedField {
        field: String,
    },
}

Reasons schema lowering can fail.

Variants

UnsupportedFieldType

A field used a type Phase 2.b’s layout pass does not yet model. The string in ty is the type head as written in source (e.g. "String", "List<Int>"), so the user sees the exact annotation that triggered the gap.

Fields

field: String

Field name that triggered the error.

ty: String

Human-readable rendering of the offending type.

UntypedField

A field declared no static type. The analyzer surfaces this as SchemaFieldUntyped in its own diagnostics; we propagate the shape so codegen can refuse to emit a layout with unknown slot widths.

Fields

field: String

Field name that triggered the error.

Trait Implementations

impl Clone for SchemaLowerError

fn clone(&self) -> SchemaLowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaLowerError

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

Formats the value using the given formatter.

impl Display for SchemaLowerError

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

Formats the value using the given formatter.

impl Eq for SchemaLowerError

impl Error for SchemaLowerError

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 SchemaLowerError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
