Struct agnes::view::DataView
[−]
[src]
pub struct DataView { /* fields omitted */ }A 'view' into a data store. The primary struct for viewing and manipulating data.
Methods
impl DataView[src]
pub fn v<L: IntoFieldList>(&self, s: L) -> DataView[src]
Generate a new subview of this DataView.
pub fn subview<L: IntoFieldList>(&self, s: L) -> Result<DataView>[src]
Generate a new subview of this DataView, generating an error if a specified field does not exist.
pub fn nrows(&self) -> usize[src]
Number of rows in this data view
pub fn is_empty(&self) -> bool[src]
Returns true if the DataView is empty (has no rows or has no fields)
pub fn nfields(&self) -> usize[src]
Number of fields in this data view
pub fn fieldnames(&self) -> Vec<&FieldIdent>[src]
Field names in this data view
pub fn get_field_type(&self, ident: &FieldIdent) -> Option<FieldType>[src]
Return the field type for specified field
pub fn field_types(&self) -> Vec<TypedFieldIdent>[src]
Return the field types (as TypedFieldIdent structs) of this DataView
pub fn has_field(&self, s: &FieldIdent) -> bool[src]
Returns true if this DataView contains this field.
pub fn rename<T, U>(&mut self, orig: T, new: U) -> Result<()> where
T: Into<FieldIdent>,
U: Into<FieldIdent>, [src]
T: Into<FieldIdent>,
U: Into<FieldIdent>,
Rename a field of this DataView.
pub fn merge(&self, other: &DataView) -> Result<DataView>[src]
Merge this DataView with another DataView object, creating a new DataView with the
same number of rows and all the fields from both source DataView objects.
pub fn join(&self, other: &DataView, join: Join) -> Result<DataStore>[src]
Combine two DataView objects using specified join, creating a new DataStore object with
a subset of records from the two source DataViews according to the join parameters.
Note that since this is creating a new DataStore object, it will be allocated new data to
store the contents of the joined DataViews.
impl DataView[src]
pub fn as_fieldview(&self) -> Option<FieldView>[src]
Create a FieldView object from a DataView object, if possible. Typically, use this on
DataView objects with only a single field; however, if the DataView object has multiple
fields, the first one will be used for this FieldView. Returns None if the DataView
has no fields (is empty).
