Enum mz_sql::session::vars::errors::VarParseError

pub enum VarParseError {
    ConstrainedParameter {
        invalid_values: Vec<String>,
        valid_values: Option<Vec<&'static str>>,
    },
    FixedValueParameter,

Expand description

Errors that can occur when parsing VarInput.

Note: This exists as a separate type from VarError because VarError wants to know about the Var we’re parsing. We could provide this info to Value::parse but it’s simpler to later enrich with VarParseError::into_var_error.

Variants§

ConstrainedParameter

Minimal version of VarError::ConstrainedParameter.

Fields

§invalid_values: Vec<String>

§valid_values: Option<Vec<&'static str>>

FixedValueParameter

Minimal version of VarError::FixedValueParameter.

InvalidParameterType

Minimal version of VarError::InvalidParameterType.

InvalidParameterValue

Minimal version of VarError::InvalidParameterValue.

Fields

§invalid_values: Vec<String>

§reason: String
