Struct CopyTableReport 

#[non_exhaustive]
pub struct CopyTableReport {
    pub rows_copied: u64,
    pub not_null_columns: usize,
    pub default_columns: usize,
    pub collated_columns: usize,
    pub assumed_primary_keys: usize,
    pub assumed_unique_constraints: usize,
    pub unpreserved: Vec<UnpreservedItem>,
}

What a Catalog::copy_table call reproduced, and what it dropped.

A copy that returns Ok has moved every row. It has not necessarily reproduced every constraint — check is_fully_preserved.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rows_copied: u64

Rows written into the destination table.

not_null_columns: usize

NOT NULL columns carried across.

default_columns: usize

DEFAULT expressions carried across.

collated_columns: usize

Explicitly collated columns carried across.

assumed_primary_keys: usize

ASSUMED PRIMARY KEY constraints carried across.

assumed_unique_constraints: usize

ASSUMED UNIQUE constraints carried across.

unpreserved: Vec<UnpreservedItem>

Schema elements that could not be reproduced.

Implementations

impl CopyTableReport

pub fn is_fully_preserved(&self) -> bool

Returns true if every constraint on the source was reproduced.

pub fn merge(&mut self, other: Self)

Folds another report into this one, for callers copying many tables.

Trait Implementations

impl Clone for CopyTableReport

fn clone(&self) -> CopyTableReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CopyTableReport

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

Formats the value using the given formatter.

impl Default for CopyTableReport

fn default() -> CopyTableReport

Returns the “default value” for a type.

impl Eq for CopyTableReport

impl PartialEq for CopyTableReport

fn eq(&self, other: &CopyTableReport) -> bool

Equality operator ==.

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

Inequality operator !=.
