Struct Processor

pub struct Processor { /* private fields */ }

Csv processor

Processor has multiple pages which can be accessed with page_name. Processor has currently selected page which name can be accessed with get_cursor method.

Implementations

Args

• page : Page name to create
• data : Csv data to store inside a page

Overwrite virtual data’s content into a imported file

• cache : whether to backup original file’s content into temp directory

Edit a column by given coordinate

This overwrite all column values with given input

pub fn edit_row( &mut self, page: &str, row_index: usize, input: &[Option<Value>], ) -> CedResult<()>

Edit a row with values

This assumes given input accords with order of a target record.

Args

• page : Page name
• row_index : Target row
• input : Inputs are array of options. Some will overwrite and none will not.

pub fn set_row( &mut self, page: &str, row_index: usize, input: &[Value], ) -> CedResult<()>

Set a row with given values

This assumes given input accords with order of a target record. This method overwrite an entire row with given values.

pub fn set_row_from_string_array( &mut self, page: &str, row_index: usize, input: &[impl AsRef<str>], ) -> CedResult<()>

Set a row with given string array

This assumes given input accords with order of a target record. This method overwrite an entire row with given values.

pub fn add_row( &mut self, page: &str, row_index: usize, values: Option<&[Value]>, ) -> CedResult<()>

Add a new row

This assumes given input accords with order of a target record.

Args

• page: Target page
• row_index : Target row
• values : Option. “None” will converted as default values.

pub fn add_row_from_string_array( &mut self, page: &str, row_index: usize, src: &[impl AsRef<str>], ) -> CedResult<()>

Add a new row but from array of strings

This assumes given input accords with order of a target record.

Args

• page: Target page
• row_index : Target row
• values : Option. “None” will converted as default values.

pub fn add_column( &mut self, page: &str, column_index: usize, column_name: &str, column_type: ValueType, limiter: Option<ValueLimiter>, placeholder: Option<Value>, ) -> CedResult<()>

Add a new column into a page

pub fn remove_row(&mut self, page: &str, row_index: usize) -> CedResult<bool>

Remove a row from a page

pub fn remove_column( &mut self, page: &str, column_index: usize, ) -> CedResult<()>

Remove a column from a page

pub fn add_column_array( &mut self, page: &str, columns: &[impl AsRef<str>], ) -> CedResult<()>

Add columns into a page

This method dosn’t require any column configurators

pub fn move_row( &mut self, page: &str, src: usize, target: usize, ) -> CedResult<()>

Move a rom from an index to a target index

pub fn move_column( &mut self, page: &str, src: usize, target: usize, ) -> CedResult<()>

Move a column from an index to a target index

pub fn rename_column( &mut self, page: &str, column: &str, new_name: &str, ) -> CedResult<()>

Rename a column into a new name

pub fn set_schema( &mut self, page: &str, path: impl AsRef<Path>, panic: bool, ) -> CedResult<()>

Apply schema into a given page

Args

• page : Page name
• path : Schema file path
• panic : Whether to panic if current value fails to qualify schema. If not every unqualified values are overwritten to default qualifying values.

Args

• page : Page name
• column : Target column name(index)
• limiter : A limiter to apply to column
