Struct UsageInfo

pub struct UsageInfo {
    pub ext_id: String,
    pub num_keys: usize,
    pub num_bytes: usize,
}

Information about the usage of a single extension.

Fields

ext_id: String

The extension id.

num_keys: usize

The number of keys the extension uses.

num_bytes: usize

The number of bytes used by the extension. This result is somewhat rough – it doesn’t bother counting the size of the extension ID, or data in the mirror, and favors returning the exact number of bytes used by the column (that is, the size of the JSON object) rather than replicating the get_bytes_in_use return value for all keys.

Trait Implementations

impl Clone for UsageInfo

fn clone(&self) -> UsageInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UsageInfo

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

Formats the value using the given formatter.

impl PartialEq for UsageInfo

fn eq(&self, other: &UsageInfo) -> 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.
