Struct RowFinder

pub struct RowFinder<'a> {
    pub rows: &'a [Row],
    /* private fields */
}

Row Finder: Find row(s) in an array of Rows that match a pre-defined condition.

Note

It’s preferable to use the RowGetter implementation instead, as that’s a little easier to work with.

Fields

rows: &'a [Row]

Represents an array of Row objects that we want to run a search on.

Implementations

impl<'a> RowFinder<'a>

pub fn new( rows: &'a [Row], column_name_to_id: &'a ColumnNameToId<'a>, column_name: &'a str, value: CellValue, cmp: Comp, ) -> Result<Self, Box<dyn Error + Send + Sync>>

Create a new RowFinder.

Note

It’s preferable to use the RowGetter implementation instead, as that’s a little easier to work with.

pub fn new_by_id( rows: &'a [Row], column_id: u64, value: CellValue, cmp: Comp, ) -> Self

Create a new RowFinder by Column Id instead of Column Name.

pub fn first<'b>(&'b self) -> Result<&'a Row, Box<dyn Error + Send + Sync>>

Find the first Row matching a specified condition.

pub fn find_all<'b>( &'b self, ) -> Result<Vec<&'a Row>, Box<dyn Error + Send + Sync>>

Find all Rows matching a specified condition.
