Struct OwningPopulationTable

pub struct OwningPopulationTable { /* private fields */ }

A standalone population table that owns its data.

Examples

use tskit::OwningPopulationTable;

let mut populations = OwningPopulationTable::default();
let rowid = populations.add_row().unwrap();
assert_eq!(rowid, 0);
assert_eq!(populations.num_rows(), 1);

An example with metadata. This requires the cargo feature "derive" for tskit.

use tskit::OwningPopulationTable;

#[derive(serde::Serialize,
         serde::Deserialize,
         tskit::metadata::PopulationMetadata)]
#[serializer("serde_json")]
struct PopulationMetadata {
    name: String,
}

let metadata = PopulationMetadata{name: "YRB".to_string()};

let mut populations = OwningPopulationTable::default();

let rowid = populations.add_row_with_metadata(&metadata).unwrap();
assert_eq!(rowid, 0);

match populations.metadata::<PopulationMetadata>(rowid) {
    // rowid is in range, decoding succeeded
    Some(Ok(decoded)) => assert_eq!(&decoded.name, "YRB"),
    // rowid is in range, decoding failed
    Some(Err(e)) => panic!("error decoding metadata: {:?}", e),
    None => panic!("row id out of range")
}

Implementations

impl OwningPopulationTable

pub fn clear(&mut self) -> TskReturnValue

Clear the table.

impl OwningPopulationTable

pub fn as_ptr(&self) -> *const tsk_population_table_t

pub fn as_mut_ptr(&mut self) -> *mut tsk_population_table_t

impl OwningPopulationTable

pub fn add_row(&mut self) -> Result<PopulationId, TskitError>

pub fn add_row_with_metadata<M>( &mut self, metadata: &M, ) -> Result<PopulationId, TskitError>

where M: PopulationMetadata,

Methods from Deref<Target = PopulationTable>

pub fn num_rows(&self) -> SizeType

Return the number of rows.

pub fn metadata<T: PopulationMetadata>( &self, row: PopulationId, ) -> Option<Result<T, TskitError>>

Retrieve decoded metadata for a row.

Returns

• Some(Ok(T)) if row is valid and decoding succeeded.
• Some(Err(_)) if row is not valid and decoding failed.
• None if row is not valid.

Errors

• TskitError::MetadataError if decoding fails.

Examples.

The big-picture semantics are the same for all table types. See crate::IndividualTable::metadata for examples.

pub fn iter(&self) -> impl Iterator<Item = PopulationTableRow> + '_

Return an iterator over rows of the table. The value of the iterator is PopulationTableRow.

pub fn lending_iter(&self) -> PopulationTableRowView<'_>

pub fn row<P: Into<PopulationId> + Copy>( &self, r: P, ) -> Option<PopulationTableRow>

Return row r of the table.

Parameters

• r: the row id.

Returns

• Some(row) if r is valid
• None otherwise

pub fn row_view<P: Into<PopulationId> + Copy>( &self, r: P, ) -> Option<PopulationTableRowView<'_>>

Return a view of row r of the table.

Parameters

• r: the row id.

Returns

• Some(row view) if r is valid
• None otherwise

Trait Implementations

impl Default for OwningPopulationTable

fn default() -> Self

Returns the “default value” for a type.

impl Deref for OwningPopulationTable

type Target = PopulationTable

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for OwningPopulationTable

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
