Trait ChainReport 

pub trait ChainReport {
    // Required methods
    fn render_table(&self) -> String;
    fn print_table(&self) -> Result<(), GraphError>;
}

Terminal tables for an option chain.

The chain renders as two box-drawn tables: one naming the symbol, the underlying price and the expiration date, then one row per strike with the columns of OPTION_CHAIN_TABLE_HEADERS and the cells of OptionData::table_cells. In colour, the headers are green, the chain’s name magenta, and the rows of strikes on a multiple of 25 points yellow.

This replaces OptionChain::show; OptionChain’s own Display is the dependency-free plain-text table.

Required Methods

fn render_table(&self) -> String

The chain’s tables as plain text, without ANSI escapes.

fn print_table(&self) -> Result<(), GraphError>

Writes the chain’s tables to stdout, coloured when stdout is a terminal.

Errors

Returns GraphError::Io when stdout cannot be written.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
