Struct columnar::string::Strings

pub struct Strings<BC = Vec<u64>, VC = Vec<u8>> {
    pub bounds: BC,
    pub values: VC,
}

A stand-in for Vec<String>.

Fields

bounds: BC

impl<BC: Clear, VC: Clear> Clear for Strings<BC, VC>

fn clear(&mut self)

Clears self, without changing its capacity.

impl<BC: Clone, VC: Clone> Clone for Strings<BC, VC>

fn clone(&self) -> Strings<BC, VC>

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

Formats the value using the given formatter.

impl<BC: Default, VC: Default> Default for Strings<BC, VC>

fn default() -> Strings<BC, VC>

Returns the “default value” for a type.

impl<'de, BC, VC> Deserialize<'de> for Strings<BC, VC>

where BC: Deserialize<'de>, VC: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, BC: FromBytes<'a>, VC: FromBytes<'a>> FromBytes<'a> for Strings<BC, VC>

fn from_bytes(bytes: &mut impl Iterator<Item = &'a [u8]>) -> Self

Reconstructs self from a sequence of correctly aligned and sized bytes slices.

impl<BC: HeapSize, VC: HeapSize> HeapSize for Strings<BC, VC>

fn heap_size(&self) -> (usize, usize)

Active (len) and allocated (cap) heap sizes in bytes. This should not include the size of self itself.

impl<'a, BC: Len + IndexAs<u64>> Index for &'a Strings<BC, Vec<u8>>

type Ref = &'a str

The type returned by the get method.

fn get(&self, index: usize) -> Self::Ref

fn last(&self) -> Option<Self::Ref>

where Self: Len,

fn iter(&self) -> IterOwn<&Self>

fn into_iter(self) -> IterOwn<Self>

where Self: Sized,

impl<'a, BC: Len + IndexAs<u64>> Index for Strings<BC, &'a [u8]>

type Ref = &'a str

The type returned by the get method.

fn get(&self, index: usize) -> Self::Ref

fn last(&self) -> Option<Self::Ref>

where Self: Len,

fn iter(&self) -> IterOwn<&Self>

fn into_iter(self) -> IterOwn<Self>

impl<BC: Len, VC> Len for Strings<BC, VC>

fn len(&self) -> usize

fn is_empty(&self) -> bool

Whether this contains no elements.

impl<BC: PartialEq, VC: PartialEq> PartialEq for Strings<BC, VC>

fn eq(&self, other: &Strings<BC, VC>) -> 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.

impl<BC: Push<u64>> Push<&String> for Strings<BC>

fn push(&mut self, item: &String)

Pushes an item onto self.

fn extend(&mut self, iter: impl IntoIterator<Item = T>)

fn extend(&mut self, iter: impl IntoIterator<Item = T>)

Pushes elements of an iterator onto self.

impl<BC, VC> Serialize for Strings<BC, VC>

where BC: Serialize, VC: Serialize,
