Struct pmtiles2::Entry

pub struct Entry {
    pub tile_id: u64,
    pub offset: u64,
    pub length: u32,
    pub run_length: u32,
}

A structure representing a directory entry.

A entry includes information on where to find either a leaf directory or one/multiple tiles.

Fields

tile_id: u64

The first tile id this entry is valid for

offset: u64

Offset (in bytes) of first byte of tile of leaf-directory data

For tiles this offset is relative to the start of the tile data sections. For leaf directories this offset is relative to the start of the leaf directory sections.

length: u32

Amount of bytes

run_length: u32

The run length indicates the amount of tiles this entry is valid for. A run length of 0 indicates that this is in fact a entry containing information of a leaf directory.

Implementations

impl Entry

pub const fn tile_id_range(&self) -> Range<u64>

Returns the range of tile ids this entry is valid for.

pub const fn is_leaf_dir_entry(&self) -> bool

Returns true if this entry is for a leaf directory and false if this entry is for tile data.

Trait Implementations

impl Clone for Entry

fn clone(&self) -> Entry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Entry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Entry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Entry

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Entry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
