Enum SchemaLookupError

Source
#[non_exhaustive]
pub enum SchemaLookupError<'coord, 'schema> { MissingType(&'coord NamedType), MissingAttribute(&'coord Name), InvalidArgumentAttribute(&'coord Name), MissingArgument(&'coord Name), InvalidType(&'schema ExtendedType), }
Expand description

The error type for SchemaCoordinate::lookup and other lookup* methods.

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.
§

MissingType(&'coord NamedType)

The requested type does not exist in the schema.

§

MissingAttribute(&'coord Name)

The requested field or enum value does not exist on its type.

§

InvalidArgumentAttribute(&'coord Name)

The requested argument can not be looked up because its type does not support arguments.

§

MissingArgument(&'coord Name)

The requested argument does not exist on its field or directive.

§

InvalidType(&'schema ExtendedType)

The requested field or enum value can not be looked up because its type does not support fields.

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().
