Struct StringTableData 

pub struct StringTableData {
    pub strings: Vec<String>,
}

The one string table a V9 snapshot carries for every ColumnData::Str in the columns section: ids[node] indexes into strings.

Up to V8 each string column carried its own strings: Vec<String> copy of the whole intern table, so a snapshot with K string columns paid for K copies. V9 writes the table once here and leaves every column’s own strings empty. The resolution rule, in seam.rs’s Str arm and in encode::archived_to_columnstore, is one sentence: if the shared table is present it is the table, otherwise the column’s own strings is — which is what keeps a pre-V9 snapshot, whose directory has no section 12, readable.

Fields

strings: Vec<String>

Trait Implementations

impl Archive for StringTableData

where Vec<String>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedStringTableData

The archived representation of this type.

type Resolver = StringTableDataResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for StringTableData

fn clone(&self) -> StringTableData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringTableData

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<StringTableData, __D> for Archived<StringTableData>

where Vec<String>: Archive, <Vec<String> as Archive>::Archived: Deserialize<Vec<String>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<StringTableData, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for StringTableData

where Vec<String>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
