Describes why type checking values for a statement failed.

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.

WrongColumnCount

Fields

actual: usize

The number of values that the Rust type provides.

asked_for: usize

The number of columns that the statement requires.

The Rust type expects actual column, but the statement requires asked_for.

NoColumnWithName

Fields

name: String

Name of the column that is missing in the statement.

The Rust type provides a value for some column, but that column is not present in the statement.

ValueMissingForColumn

Fields

name: String

Name of the column for which the Rust type doesn’t provide a value.

A value required by the statement is not provided by the Rust type.

ColumnNameMismatch

Fields

rust_column_name: String

Name of the column, as expected by the Rust type.

db_column_name: String

Name of the column for which the DB requested a value.

A different column name was expected at given position.
