Enum ValueRef 

pub enum ValueRef<'a> {
    Null,
    Integer(i64),
    Float(f64),
    Text(&'a str),
    Blob(&'a [u8]),
}

Borrowed SQLite value view.

Variants

Null

SQL NULL.

Integer(i64)

Borrowed 64-bit integer.

Float(f64)

Borrowed 64-bit floating point.

Text(&'a str)

Borrowed UTF-8 text.

Blob(&'a [u8])

Borrowed bytes.

Implementations

impl<'a> ValueRef<'a>

pub fn value_type(&self) -> ValueType

Return the SQLite value type tag for this borrowed value.

pub fn as_i64(&self) -> Option<i64>

Borrow the integer payload when this is ValueRef::Integer.

pub fn as_f64(&self) -> Option<f64>

Borrow the float payload when this is ValueRef::Float.

pub fn as_str(&self) -> Option<&'a str>

Borrow the text payload when this is ValueRef::Text.

pub fn as_blob(&self) -> Option<&'a [u8]>

Borrow the blob payload when this is ValueRef::Blob.

pub fn to_owned(&self) -> Value

Copy this borrowed value into an owned Value.

pub unsafe fn from_raw_text(raw: RawBytes) -> ValueRef<'a>

Safety

Caller must ensure raw points to valid bytes for the duration of 'a.

If raw is valid UTF-8 this returns ValueRef::Text; otherwise it falls back to ValueRef::Blob to avoid unchecked UTF-8 assumptions.

pub unsafe fn from_raw_blob(raw: RawBytes) -> ValueRef<'a>

Safety

Caller must ensure raw points to valid bytes for the duration of 'a.

Trait Implementations

impl<'a> Clone for ValueRef<'a>

fn clone(&self) -> ValueRef<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ValueRef<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for ValueRef<'a>

fn eq(&self, other: &ValueRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
