Struct odbc_api::ColumnDescription

source · [−]

pub struct ColumnDescription {
    pub name: Vec<SqlChar>,
    pub data_type: DataType,
    pub nullability: Nullability,
}

Expand description

Describes the type and attributes of a column.

Fields

name: Vec<SqlChar>

Column name. May be empty if unavailable.

data_type: DataType

Type of the column

nullability: Nullability

Indicates whether the column is nullable or not.

Implementations

source

impl ColumnDescription

source

pub fn name_to_string(&self) -> Result<String, DecodeUtf16Error>

Converts the internal UTF16 representation of the column name into UTF8 and returns the result as a String.

source

pub fn could_be_nullable(&self) -> bool

true if the column is Nullable or it is not know whether the column is nullable. false if and only if the column is NoNulls.
