Enum GridError 

#[non_exhaustive]
pub enum GridError {
    TooLarge {
        rows: u64,
        cols: u64,
    },
    Overlap {
        at: GridCoord,
    },
    OverhangsBottom {
        at: GridCoord,
    },
    NotTiled {
        at: GridCoord,
    },
}

Why a table’s cells do not tile a well-formed logical grid.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooLarge

The grid would exceed MAX_GRID_POSITIONS.

Fields

rows: u64

Derived (or partially derived) row count.

cols: u64

Derived (or partially derived) column count.

Overlap

A cell’s span covers a position already covered by another cell.

Fields

at: GridCoord

First doubly-covered position encountered.

OverhangsBottom

A cell’s row_span extends past the table’s last row.

Fields

at: GridCoord

First covered position outside the grid.

NotTiled

A position inside the grid rectangle is covered by no cell.

Fields

at: GridCoord

First uncovered position (row-major scan order).

Trait Implementations

impl Clone for GridError

fn clone(&self) -> GridError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GridError

impl Debug for GridError

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

Formats the value using the given formatter.

impl Eq for GridError

impl Error for GridError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for GridError

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

Equality operator ==.

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

Inequality operator !=.
