Struct mentat_db::types::DB

pub struct DB {
    pub partition_map: PartitionMap,
    pub schema: Schema,
}

Represents the metadata required to query from, or apply transactions to, a Mentat store.

See https://github.com/mozilla/mentat/wiki/Thoughts:-modeling-db-conn-in-Rust.

Fields

partition_map: PartitionMap

Map partition name->Partition.

TODO: represent partitions as entids.

schema: Schema

The schema of the store.

Methods

impl DB

pub fn new(partition_map: PartitionMap, schema: Schema) -> DB

Trait Implementations

impl Clone for DB

fn clone(&self) -> DB

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DB

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for DB

fn default() -> DB

Returns the "default value" for a type.

impl Eq for DB

impl Hash for DB

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl Ord for DB

fn cmp(&self, __arg_0: &DB) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl PartialOrd for DB

fn partial_cmp(&self, __arg_0: &DB) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &DB) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &DB) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &DB) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &DB) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq for DB

fn eq(&self, __arg_0: &DB) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &DB) -> bool

This method tests for !=.
