Struct Page 

#[non_exhaustive]
pub struct Page {
    pub start: usize,
    pub rows: Vec<Vec<Value>>,
    pub total: Option<usize>,
    pub more: bool,
    pub columns: Vec<usize>,
    pub frozen: usize,
    pub column_total: usize,
}

The rows one window shows, from VirtualTable::page.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

start: usize

The 0-based index of the first row shown. It is the table’s offset, moved back when that is past the end of a source that knows its length.

rows: Vec<Vec<Value>>

The rows shown, each with one cell per column shown (see columns).

total: Option<usize>

How many rows the source has: its own count, or the end when this window reached it.

more: bool

Whether a row is known to follow the window.

columns: Vec<usize>

The 0-based indices of the columns shown, in order: the frozen ones, then the window’s. Every column when the table has no column window.

frozen: usize

How many of columns are frozen.

column_total: usize

How many columns the table has.

Implementations

impl Page

pub fn range(&self) -> Range<usize>

The 0-based indices of the rows shown.

pub fn column_range(&self) -> Range<usize>

The 0-based indices of the columns shown after the frozen ones.

pub fn column_position(&self, ascii: bool) -> Option<String>

Where the column window is, in words, when it leaves columns out: columns 41–60 of 2,000 (counted from 1, frozen columns aside), or column 7 of 12. None when every column is shown. ascii writes the range with - instead of –.

pub fn position(&self, ascii: bool) -> String

Where the window is, in words: rows 1,001–1,040 of 1,000,000, rows 1–40 of 41+ when the source cannot count past the window, no rows, or no rows from 1,001 past the end of an uncounted source. ascii writes the range with - instead of –.
