Struct FragmentTreeChild 

pub struct FragmentTreeChild {
    pub path: String,
    pub base_id: Option<u32>,
    pub min_key: u64,
    pub num_keys: u64,
    pub height: u32,
    pub num_children: u32,
    pub total_rows: u64,
    pub object_size: u64,
    pub materialized_through_action_sequence: u64,
    pub visible_rows: u64,
}

Children are ordered by min_key. A child owns [min_key, next min_key); the last child inherits its parent’s upper bound.

Fields

path: String

Tree object path relative to its resolved dataset.

base_id: Option<u32>

Absent inherits the containing object’s dataset. Otherwise matches BasePath.id in Manifest.base_paths; zero is a valid ID.

min_key: u64

Inclusive lower bound of this child’s fragment-ID range. It need not equal an ID currently stored in the child.

num_keys: u64

Fragment count in this subtree, including this object’s buffer.

height: u32

Edges from this object to its leaves. Zero for a leaf.

num_children: u32

Direct child count. Zero for a leaf.

total_rows: u64

Physical rows in this subtree, including this object’s buffer.

object_size: u64

Stored byte length of the child object.

materialized_through_action_sequence: u64

Every mutation for this leaf’s range at or below this value has been applied, and none remain buffered above it. Zero means none. Must be 0 for interiors.

visible_rows: u64

Visible rows in this subtree, including this object’s buffer.

impl Message for FragmentTreeChild

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl Name for FragmentTreeChild

const NAME: &'static str = "FragmentTreeChild"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "lance.table"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for FragmentTreeChild

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

Equality operator ==.

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

Inequality operator !=.
