Enum rusqlite::types::Value
[−]
[src]
pub enum Value { Null, Integer(i64), Real(f64), Text(String), Blob(Vec<u8>), }
Dynamic type value (http://sqlite.org/datatype3.html) Value's type is dictated by SQLite (not by the caller).
Variants
Null
The value is a NULL
value.
Integer(i64)
The value is a signed integer.
Real(f64)
The value is a floating point number.
Text(String)
The value is a text string.
Blob(Vec<u8>)
The value is a blob of data

impl PartialEq for Value
[src]
fn eq(&self, __arg_0: &Value) -> bool
This method tests for self
and other
values to be equal, and is used by ==
. Read more

impl FromSql for Value
[src]
unsafe fn column_result(stmt: *mut sqlite3_stmt, col: c_int) -> Result<Value>
unsafe fn column_has_valid_sqlite_type(_: *mut sqlite3_stmt, _: c_int) -> bool
FromSql types can implement this method and use sqlite3_column_type to check that the type reported by SQLite matches a type suitable for Self. This method is used by Row::get_checked
to confirm that the column contains a valid type before attempting to retrieve the value. Read more
